UniProt functional annotation for Q15672



	UniProt functional annotation for Q15672

UniProt code: Q15672.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: Acts as a transcriptional regulator. Inhibits myogenesis by sequestrating E proteins, inhibiting trans-activation by MEF2, and inhibiting DNA-binding by MYOD1 through physical interaction. This interaction probably involves the basic domains of both proteins. Also represses expression of proinflammatory cytokines such as TNFA and IL1B. Regulates cranial suture patterning and fusion. Activates transcription as a heterodimer with E proteins. Regulates gene expression differentially, depending on dimer composition. Homodimers induce expression of FGFR2 and POSTN while heterodimers repress FGFR2 and POSTN expression and induce THBS1 expression. Heterodimerization is also required for osteoblast differentiation. Represses the activity of the circadian transcriptional activator: NPAS2-ARNTL/BMAL1 heterodimer (By similarity). {ECO:0000250|UniProtKB:P26687, ECO:0000269|PubMed:12553906, ECO:0000269|PubMed:25981568}.

Subunit: Efficient DNA binding requires dimerization with another bHLH protein. Homodimer or heterodimer with E proteins such as TCF3. ID1 binds preferentially to TCF3 but does not interact efficiently with TWIST1 so ID1 levels control the amount of TCF3 available to dimerize with TWIST1 and thus determine the type of dimer formed (By similarity). {ECO:0000250|UniProtKB:P26687}.

Subcellular location: Nucleus.

Tissue specificity: Subset of mesodermal cells.

Disease: Saethre-Chotzen syndrome (SCS) [MIM:101400]: A craniosynostosis syndrome characterized by coronal synostosis, brachycephaly, low frontal hairline, facial asymmetry, hypertelorism, broad halluces, and clinodactyly. {ECO:0000269|PubMed:11754069, ECO:0000269|PubMed:8988166, ECO:0000269|PubMed:8988167}. Note=The disease is caused by variants affecting the gene represented in this entry.

Disease: Robinow-Sorauf syndrome (RSS) [MIM:180750]: An autosomal dominant syndrome characterized by craniosynostosis, asymmetry of orbits, flat face, hypertelorism, a thin, long, and pointed nose, shallow orbits, strabismus, and broad great toes with a duplication of the distal phalanx. RSS is clinically similar to Saethre-Chotzen syndrome, with the most characteristic additional feature in Robinow- Sorauf syndrome being a bifid or partially duplicated hallux. {ECO:0000269|PubMed:10465122}. Note=The disease is caused by variants affecting the gene represented in this entry.

Disease: Craniosynostosis 1 (CRS1) [MIM:123100]: A primary abnormality of skull growth involving premature fusion of one or more cranial sutures. The growth velocity of the skull often cannot match that of the developing brain resulting in an abnormal head shape and, in some cases, increased intracranial pressure, which must be treated promptly to avoid permanent neurodevelopmental disability. {ECO:0000269|PubMed:17343269}. Note=The disease is caused by variants affecting the gene represented in this entry.

Disease: Sweeney-Cox syndrome (SWCOS) [MIM:617746]: An autosomal dominant syndrome characterized by facial dysostosis, including hypertelorism, deficiencies of the eyelids and facial bones, cleft palate/velopharyngeal insufficiency, and low-set cupped ears. {ECO:0000269|PubMed:28369379}. Note=The disease is caused by variants affecting the gene represented in this entry.
