fourth malignant brain tumor (MBT) repeat found in the Drosophila melanogaster Polycomb protein Sfmbt (dSfmbt)-like family; The dSfmbt-like family includes Drosophila melanogaster Scm-like with four MBT domain-containing protein 1 (dSfmbt), as well as its two vertebrate homologs, MBT domain-containing protein 1 (MBTD1) and Lethal(3)malignant brain tumor-like protein 2 (L3MBTL2). dSfmbt is a Polycomb group (PcG) repressor involved in epigenetic regulation of gene expression. MBTD1 and L3MBTL2, also called L(3)mbt-like protein 2, are putative PcG proteins that specifically bind to monomethylated and dimethylated 'Lys-20' on histone H4. L3MBTL2 also binds histone H3 peptides which are monomethylated or dimethylated on 'Lys-4', 'Lys-9' or 'Lys-27'. Members of this family contain four MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine. This model corresponds to the fourth MBT repeat that contains the semi-aromatic cage that binds methylated lysine residues.

second malignant brain tumor (MBT) repeat found in the Polycomb protein sex comb on midleg family; The Sex comb on midleg (Scm) family of Polycomb proteins includes Drosophila melanogaster Scm protein, as well as two vertebrate homologs of Scm, Polycomb protein sex comb on midleg homolog 1 (SCMH1) and sex comb on midleg-like protein 2 (SCML2). Scm is a putative zinc finger protein that functions as a transcriptional regulator which represses multiple homeotic genes during embryonic stages. It coordinates Polycomb group (PcG) complexes, PRC1 (PcG-repressive complex 1) or PRC2 (PcG-repressive complex 2), and polymerizes to produce broad domains of PcG silencing. Both SCMH1 and SCML2 are components of PRC1, which acts as an E3 ubiquitin ligase both for histone H2A to silence transcription and for geminin to regulate its stability. SCMH1 provides the complex with an interaction domain for geminin. SCML2 is a germline-specific Polycomb protein that acts as a critical regulator of heterochromatin organization in spermatogenesis. Members of this family contain two MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine.

fourth malignant brain tumor (MBT) repeat found in the Scm-like with four MBT domains protein (SFMBT) family; The SFMBT family includes SFMBT1 and SFMBT2. SFMBT1, also called renal ubiquitous protein 1, is a transcriptional repressor protein that selectively binds the N-terminal tail of histone H3 and functions as a chromatin reader in regulating epigenetic silencing and the myogenic gene program. It mediates the recruitment of corepressor complexes to target genes, followed by chromatin compaction and repression of transcription. SFMBT2, also called Scm-like with 4 MBT domains protein 2, is a transcriptional repressor of the HOXB13 gene. It is required for trophoblast maintenance and placenta development. It also negatively regulates cell migration and invasion in prostate cancer cells. Members of this family contain four MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine. This model corresponds to the fourth MBT repeat that does not contain a semi-aromatic cage and may not bind methylated lysine residues.

third malignant brain tumor (MBT) repeat found in the Lethal(3)malignant brain tumor-like protein 1 (L3MBTL1)-like family; The L3MBTL1-like family includes L3MBTL1, L3MBTL3, and L3MBTL4. L3MBTL1, also called L(3)mbt-like, or L(3)mbt protein homolog, is a Polycomb group (PcG) protein that functions as a 'reader' of a network of post-translational modifications by specifically recognizing and binding mono- and dimethyllysine residues on target proteins. It acts as a chromatin compaction factor by binding mono- and dimethylated histone H1b/HIST1H1E at 'Lys-26' (H1bK26me1 and H1bK26me2) and histone H4 at 'Lys-20' (H4K20me1 and H4K20me2), leading to condensed chromatin and repressed transcription. L3MBTL3, also called L(3)mbt-like protein 3, or MBT-1, is a PcG protein that recognizes mono- and dimethylated lysine residues on histone tails. It also acts as a methyl-binding protein that binds the K142-methylated DNMT1 and recruits a novel CRL4(DCAF5) ubiquitin ligase to degrade DNMT1. L3MBTL4, also called L(3)mbt-like protein 4, or L3mbt-like 4, is a PcG protein that may act as a tumor suppressor. Members of this family contain three MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones.

second malignant brain tumor (MBT) repeat found in sex comb on midleg-like protein 2 (SCML2) and similar proteins; SCML2 is a homolog of Drosophila Sex comb on midleg (Scm). It is a component of PRC1 (Polycomb repressive complex 1), which acts as an E3 ubiquitin ligase, both for histone H2A to silence transcription and for geminin to regulate its stability. SCML2 is a germline-specific Polycomb protein that acts as a critical regulator of heterochromatin organization in spermatogenesis. SCML2 contains two MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones.

first malignant brain tumor (MBT) repeat found in the Lethal(3)malignant brain tumor-like protein 1 (L3MBTL1)-like family; The L3MBTL1-like family includes L3MBTL1, L3MBTL3, and L3MBTL4. L3MBTL1, also called L(3)mbt-like, or L(3)mbt protein homolog, is a Polycomb group (PcG) protein that functions as a 'reader' of a network of post-translational modifications by specifically recognizing and binding mono- and dimethyllysine residues on target proteins. It acts as a chromatin compaction factor by binding mono- and dimethylated histone H1b/HIST1H1E at 'Lys-26' (H1bK26me1 and H1bK26me2) and histone H4 at 'Lys-20' (H4K20me1 and H4K20me2), leading to condensed chromatin and repressed transcription. L3MBTL3, also called L(3)mbt-like protein 3, or MBT-1, is a PcG protein that recognizes mono- and dimethylated lysine residues on histone tails. It also acts as a methyl-binding protein that binds the K142-methylated DNMT1 and recruits a novel CRL4(DCAF5) ubiquitin ligase to degrade DNMT1. L3MBTL4, also called L(3)mbt-like protein 4, or L3mbt-like 4, is a PcG protein that may act as a tumor suppressor. Members of this family contain three MBT (malignant brain tumor) repeats.

malignant brain tumor (MBT) repeat; The MBT repeat is a protein module that recognizes methylated lysine residues on histones and are thought to affect a variety of chromatin processes, including transcription. It exists as tandem repeats and is found in a number of nuclear proteins such as Drosophila sex comb on midleg protein. In the human genome, there are at least 9 MBT repeat proteins, each containing two, three or four MBT repeats. MBT repeat proteins use a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine (monomethyllysine and/or dimethyllysine).

fourth malignant brain tumor (MBT) repeat found in the Scm-like with four MBT domains protein (SFMBT) family; The SFMBT family includes SFMBT1 and SFMBT2. SFMBT1, also called renal ubiquitous protein 1, is a transcriptional repressor protein that selectively binds the N-terminal tail of histone H3 and functions as a chromatin reader in regulating epigenetic silencing and the myogenic gene program. It mediates the recruitment of corepressor complexes to target genes, followed by chromatin compaction and repression of transcription. SFMBT2, also called Scm-like with 4 MBT domains protein 2, is a transcriptional repressor of the HOXB13 gene. It is required for trophoblast maintenance and placenta development. It also negatively regulates cell migration and invasion in prostate cancer cells. Members of this family contain four MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine. This model corresponds to the fourth MBT repeat that does not contain a semi-aromatic cage and may not bind methylated lysine residues.

third malignant brain tumor (MBT) repeat found in Drosophila melanogaster Polycomb protein Sfmbt (dSfmbt) and similar proteins; dSfmbt, also called Scm-like with four MBT domain-containing protein 1, is a Polycomb group repressor involved in epigenetic regulation of gene expression. dSfmbt contains four MBT (malignant brain tumor) repeats. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine. This model corresponds to the third MBT repeat that does not seem to contain a semi-aromatic cage and may not bind methylated lysine residues.
