Background Information

ID4 (inhibitor of DNA binding 4) negatively regulates the basic helix-loop-helix (bHLH) transcription factors by forming heterodimers and inhibiting their DNA binding and transcriptional activity. (PMID: 19783986). ID4 levels dictate the stem cell state in mouse spermatogonia (PMID: 28087628). It is involved in the regulation of many cellular processes during both prenatal development and tumorigenesis. ID4 can be detected 25-30 kDa (PMID: 34108007, PMID: 31847356).
