CIRBP Protein, Human (His)
Based on 1 publication(s) in Google Scholar
CIRBP is a cold-induced mRNA-binding protein that plays a key role in cellular responses to genotoxic stress, exerting a protective effect by stabilizing transcripts of genes critical for cell survival. As a translation activator, CIRBP appears to be critical for cold-induced inhibition of cell proliferation. CIRBP Protein, Human (His) is the recombinant human-derived CIRBP protein, expressed by E. coli , with N-His labeled tag.

Cold-Inducible RNA Binding Protein (CIRBP) is a crucial player in the cellular response to genotoxic stress, exerting a protective role by stabilizing transcripts of genes associated with cell survival. As a translational activator, CIRBP is involved in the cold-induced suppression of cell proliferation and binds specifically to the 3'-untranslated regions (3'-UTRs) of stress-responsive transcripts like RPA2 and TXN. It acts as a translational repressor, promoting the assembly of stress granules (SGs) when overexpressed. Additionally, CIRBP interacts with EIF4G1 and associates with ribosomes, emphasizing its multifaceted involvement in cellular stress responses and RNA processing (
