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.

Biological Context

Subcellular Location: Cytoplasm; Nucleus

Product Specifications

Recombinant Human DNA-binding protein inhibitor ID-1 (ID1) is a recombinant protein from Homo sapiens (Human), expressed in E.coli, covering amino acids 1-155aa, with N-terminal 6xHis-SUMO-tagged tag, molecular weight 32.1kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.
