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.
