Background CIRBP, also known as cold-inducible RNA-binding protein, plays a protective role in the genotoxic stress response by stabilizing transcripts of genes involved in cell survival. CIRBP responds to a wide array of cellular stresses, including short wavelength ultraviolet light (UVC), at the transcriptional and post-translational level. It acts as a translational activator.CIRBP can bind the 3 translated region of specific transcripts to stabilize them and facilitate their transport to ribosomes for translation. CIRBP affects NF-κB signaling as opposed to IL1B mRNA stability directly.
