Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The Id1 protein also known as Inhibitor of Differentiation 1 functions as a helix-loop-helix (HLH) transcription factor. It belongs to the family of inhibitor of differentiation proteins and weighs approximately 16 kDa. It lacks a basic DNA-binding domain which causes it to prevent transcription when it forms heterodimers with other HLH proteins. Id1 shows expression in various tissues but has noticeably high levels in embryonic and adult tissues involved in developmental processes.
Biological function summary

The Id1 protein plays significant roles in cellular differentiation proliferation and senescence. It does not function within a larger complex but acts as a suppressor of basic HLH transcription factors influencing cell differentiation pathways. Particularly it inhibits functions of factors that promote differentiation allowing cells to maintain a proliferative state. This inhibition capability marks Id1 as an important regulator in development and adult tissue maintenance.

Pathways

The Id1 protein influences key processes by interacting with the TGF-β (transforming growth factor-beta) pathway. It helps regulate cellular responses to growth factors that control cell cycle and apoptosis. In addition the protein has connections to the Notch signaling pathway which is important in cell fate determination. Through these pathways Id1 interacts with proteins such as Smad and Notch receptors highlighting its influence on developmental and immune responses.

Id1 has been linked to cancer and neurodegenerative diseases. Its dysregulation often leads to abnormal cell proliferation and resistance to differentiation processes that are hallmarks in cancer progression. Related proteins like c-Myc have interactions with Id1 in cancer endorsing cell cycle advancement. Additionally elevated Id1 expression connects to neurodegenerative conditions as it may disrupt normal neuronal differentiation linking to proteins such as NF-kB involved in cell survival and inflammation.

General info

Function

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. Inhibits skeletal muscle and cardiac myocyte differentiation. Regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-BMAL1 heterodimer (By similarity).
