ID is so-called Inhibitor of differentiation/DNA binding proteins
ID proteins is frequently deregulated in advanced human malignancies.
ID proteins can participate in blocking differentiation, increasing proliferation, tissue invasiveness, and angiogenesis.
PMID:17615296
Through constitutive association with bHLH E12/E47 proteins, Id proteins maintain epithelial phenotypes by repressing the function of E12/E47, which acts as a repressor of E-cadherin.
Down-regulation of ID1 by Smad2/3/ATF3 complex and of ID2 as well as ID3 by TGFB thus relieve this inhibition, permitting conversion of epithelial cells to cells with mesenchymal phenotypes
TGFB induces ETS1 transcriptional expression.
TGFB represses ID2 and ID3 transcriptional expression (PMID:15121845 and PMID:15181457)
ID2 may regulate the function of Ets1 to modulate the transcription of ZEB1 and ZEB2 without alteration of the transcription of Ets1.
Ets1 may act as an inducer of ZEB1 in collaboration with E47 (TCF3)
