 761-950 9.02e-134

cyclin box found in retinoblastoma-like protein 2 (RBL2) and similar proteins; RBL2, also called 130 kDa retinoblastoma-associated protein (p130), retinoblastoma-related protein 2 (RBR-2), or pRb2, is a key regulator of entry into cell division. It is directly involved in heterochromatin formation by maintaining overall chromatin structure, especially that of constitutive heterochromatin by stabilizing histone methylation. RBL2 recruits and targets histone methyltransferases KMT5B and KMT5C, leading to epigenetic transcriptional repression. It controls histone H4 'Lys-20' trimethylation. It probably acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. It may also act as a tumor suppressor. RBL2 contains one cyclin box. The cyclin box is a protein binding domain.

 596-736 1.75e-06

N-terminal domain of transcription factor Specificity Proteins (SP) 1-4; Specificity Proteins (SPs) are transcription factors that are involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. There are many SPs in vertebrates (9 SPs in humans and mice, 7 SPs in chicken, and 11 SPs in teleost fish), but arthropods only have 3 SPs. SPs belong to a family of proteins, called the SP/Kruppel or Krueppel-like Factor (KLF) family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. SP factors preferentially bind GC boxes, while KLFs bind CACCC boxes. Another characteristic hallmark of SP factors is the presence of the Buttonhead (BTD) box CXCPXC, just N-terminal to the zinc fingers. The function of the BTD box is unknown, but it is thought to play an important physiological role. Another feature of most SP factors is the presence of a conserved amino acid stretch, the so-called SP box, located close to the N-terminus. SP factors may be separated into three groups based on their domain architecture and the similarity of their N-terminal transactivation domains: SP1-4, SP5, and SP6-9. The transactivation domains between the three groups are not homologous to one another. SP1-4 have similar N-terminal transactivation domains characterized by glutamine-rich regions, which, in most cases, have adjacent serine/threonine-rich regions. This model represents the N-terminal domain of SP1-4.

 761-950 9.02e-134

cyclin box found in retinoblastoma-like protein 2 (RBL2) and similar proteins; RBL2, also called 130 kDa retinoblastoma-associated protein (p130), retinoblastoma-related protein 2 (RBR-2), or pRb2, is a key regulator of entry into cell division. It is directly involved in heterochromatin formation by maintaining overall chromatin structure, especially that of constitutive heterochromatin by stabilizing histone methylation. RBL2 recruits and targets histone methyltransferases KMT5B and KMT5C, leading to epigenetic transcriptional repression. It controls histone H4 'Lys-20' trimethylation. It probably acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. It may also act as a tumor suppressor. RBL2 contains one cyclin box. The cyclin box is a protein binding domain.

cyclin box found in Arabidopsis thaliana retinoblastoma-related protein 1 (AtRBR1) and similar proteins; AtRBR1 is a key regulator of entry into cell division. It acts as a transcription repressor of E2F target genes, whose activity is required for progress from the G1 to the S phase of the cell cycle. AtRBR1 plays a central role in the mechanism controlling meristem cell differentiation, cell fate establishment and cell fate maintenance during organogenesis and gametogenesis. AtRBR1 contains one cyclin box. The cyclin box is a protein binding domain.

N-terminal domain of transcription factor Specificity Protein (SP) 1-4 from arthropods; Specificity Proteins (SPs) are transcription factors that are involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. There are many SPs in vertebrates (9 SPs in humans and mice, 7 SPs in the chicken, and 11 SPs in teleost fish), but arthropods only have 3 SPs. One SP is clade SP1-4, which is expressed ubiquitously throughout development. SP1-4 belongs to a family of proteins, called the SP/Kruppel or Krueppel-like Factor (KLF) family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. SP factors preferentially bind GC boxes, while KLFs bind CACCC boxes. Another characteristic hallmark of SP factors is the presence of the Buttonhead (BTD) box CXCPXC, just N-terminal to the zinc fingers. The function of the BTD box is unknown, but it is thought to play an important physiological role. Another feature of most SP factors is the presence of a conserved amino acid stretch, the so-called SP box, located close to the N-terminus. This model represents the N-terminal domain of SP1-4 from arthropods.
