Mol. Genet. 26:2118-2132(2017). CC -!- FUNCTION: Acts as a transcriptional regulator. Inhibits myogenesis by CC sequestrating E proteins, inhibiting trans-activation by MEF2, and CC inhibiting DNA-binding by MYOD1 through physical interaction. This CC interaction probably involves the basic domains of both proteins. Also CC represses expression of pro-inflammatory cytokines such as TNFA and CC IL1B. Regulates cranial suture patterning and fusion. Activates CC transcription as a heterodimer with E proteins. Regulates gene CC expression differentially, depending on dimer composition. Homodimers CC induce expression of FGFR2 and POSTN while heterodimers repress FGFR2 CC and POSTN expression and induce THBS1 expression. Heterodimerization is CC also required for osteoblast differentiation. Represses the activity of CC the circadian transcriptional activator: NPAS2-BMAL1 heterodimer (By CC similarity). {ECO:0000250|UniProtKB:P26687, CC ECO:0000269|PubMed:12553906, ECO:0000269|PubMed:25981568}. CC -!- SUBUNIT: Efficient DNA binding requires dimerization with another bHLH CC protein. Homodimer or heterodimer with E proteins such as TCF3. ID1 CC binds preferentially to TCF3 but does not interact efficiently with CC TWIST1 so ID1 levels control the amount of TCF3 available to dimerize CC with TWIST1 and thus determine the type of dimer formed (By CC similarity). {ECO:0000250|UniProtKB:P26687}.

CC -!- DISEASE: Saethre-Chotzen syndrome (SCS) [MIM:101400]: A CC craniosynostosis syndrome characterized by coronal synostosis, CC brachycephaly, low frontal hairline, facial asymmetry, hypertelorism, CC broad halluces, and clinodactyly. {ECO:0000269|PubMed:11754069, CC ECO:0000269|PubMed:8988166, ECO:0000269|PubMed:8988167}.
