Gene Gene information from NCBI Gene database.
Entrez ID 3399
Gene name Inhibitor of DNA binding 3
Gene symbol ID3
Synonyms (NCBI Gene)
HEIR-1bHLHb25
Chromosome 1
Chromosome location 1p36.12
Summary The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with other HLH proteins. However, the encoded protein lacks a basic DNA-binding domain and therefore inhibits the DNA binding of any HLH protein with which it
