Description

Description:

hes family bHLH transcription factor 3 [Source:HGNC Symbol;Acc:HGNC:26226]

Entrez Summary

Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; E-box binding activity; and N-box binding activity. Predicted to be involved in several processes, including Notch signaling pathway; negative regulation of neuron differentiation; and regulation of neurogenesis. Predicted to act upstream of or within several processes, including nervous system development; regulation of timing of neuron differentiation; and regulation of transcription by RNA polymerase II. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

It has been proposed [PUBMED:2493990] that this domain is formed of two amphipathic helices joined by a variable length linker region that could form a loop. This 'helix-loop-helix' (HLH) domain mediates protein dimerization and has been found in the proteins listed below [PUBMED:1521738]. Most of these proteins have an extra basic region of about 15 amino acid residues that is adjacent to the HLH domain and specifically binds to DNA. They are refered as basic helix-loop-helix proteins (bHLH), and are classified in two groups: class A (ubiquitous) and class B (tissue-specific). Members of the bHLH family bind variations on the core sequence 'CANNTG', also refered to as the E-box motif. The homo- or heterodimerization mediated by the HLH domain is independent of, but necessary for DNA binding, as two basic regions are required for DNA binding activity. The HLH proteins lacking the basic domain (Emc, Id) function as negative regulators, since they form heterodimers, but fail to bind DNA. The hairy-related proteins (hairy, E(spl), deadpan) also repress transcription although they can bind DNA. The proteins of this subfamily act together with co-repressor proteins, like groucho, through their C-terminal motif WRPW.", "database": "PfamA", "aliStart": 1, "scoreName": "E-value", "accession": "PF00010.24", "start": 1, "score": 4.9e-12, "identifier": "Helix-loop-helix DNA-binding domain", "type": "DBD", "aliEnd": 50}}], "length": 187}
