TLX2 T cell leukemia homeobox 2 [Homo sapiens (human)] - Gene

Summary

Official Symbol: TLX2provided by HGNC
Official Full Name: T cell leukemia homeobox 2provided by HGNC
Primary source: HGNC:HGNC:5057
See related: Ensembl:ENSG00000115297 MIM:604240; AllianceGenome:HGNC:5057
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: NCX; HOX11L1
Summary: This gene is a member of an orphan homeobox-containing transcription factor family. Studies of the mouse ortholog have shown that the encoded protein is crucial for the development of the enteric nervous system; in humans, loss-of-function may play a role in tumorigenesis of gastrointestinal stromal tumors.

NCX-TRPC channel interaction constitutes an important functional unit in receptor-mediated divalent calcium ion influx in neuronal cells.
Title: Selective interference with TRPC3/6 channels disrupts OX1 receptor signalling via NCX and reveals a distinct calcium influx pathway.
NCX is functionally expressed in developing ventricular human embryonic stem cell-derived ventricular cardiomyocytes and contributes to their excitation-contraction coupling.
Title: Na+/Ca2+ exchanger is a determinant of excitation-contraction coupling in human embryonic stem cell-derived ventricular cardiomyocytes.
This paper describes sequencing and comparison of 5' flanking regions of the gene, and expression in several neuroblastoma cell lines, in both mouse and human.
Title: An enhancer element for expression of the Ncx (Enx, Hox11L1) gene in neural crest-derived cells.
TLX2 is an orphan homeodomain transcription factor whose expression is mainly associated with tissues derived from neural crest cells.

These results support the PHOX2B-TLX2 promoter interaction, suggesting a physiological role in the transcription-factor cascade underlying the differentiation of neuronal lineages of the Autonomic Nervous System during human embryogenesis.
Title: The TLX2 homeobox gene is a transcriptional target of PHOX2B in neural-crest-derived cells.
Alignment of sequences obtained from rat, human, and mouse indicates that putative regulatory elements of the Hox11L1 gene are conserved in rat, mice, and humans.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
