External Ids for ID3 Gene
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 interacts. [provided by RefSeq, Aug 2011]
GeneCards Summary for ID3 Gene
ID3 (Inhibitor Of DNA Binding 3, Dominant Negative Helix-Loop-Helix Protein) is a Protein Coding gene. Among its related pathways are Adipogenesis and TGF-beta/Smad Signaling. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription corepressor activity. An important paralog of this gene is ID1.
UniProtKB/Swiss-Prot for ID3 Gene
Transcriptional regulator (lacking a basic DNA binding domain) which negatively regulates the basic helix-loop-helix (bHLH) transcription factors by forming heterodimers and inhibiting their DNA binding and transcriptional activity. Implicated in regulating a variety of cellular processes, including cellular growth, senescence, differentiation, apoptosis, angiogenesis, and neoplastic transformation. Involved in myogenesis by inhibiting skeletal muscle and cardiac myocyte differentiation and promoting muscle precursor cells proliferation. Inhibits the binding of E2A-containing protein complexes to muscle creatine kinase E-box enhancer. Regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-ARNTL/BMAL1 heterodimer.
