CC -!- FUNCTION: Cold-inducible mRNA binding protein that plays a protective
CC role in the genotoxic stress response by stabilizing transcripts of
CC genes involved in cell survival. Acts as a translational activator.
CC Seems to play an essential role in cold-induced suppression of cell
CC proliferation. Binds specifically to the 3'-untranslated regions (3'-
CC UTRs) of stress-responsive transcripts RPA2 and TXN. Acts as a
CC translational repressor. Promotes assembly of stress granules (SGs),
CC when overexpressed (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with EIF4G1. Associates with ribosomes (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm. Cytoplasm.
CC Note=Translocates from the nucleus to the cytoplasm after exposure to
CC UV radiation. Translocates from the nucleus to the cytoplasm into
CC stress granules upon various cytoplasmic stresses, such as osmotic and
CC heat shocks. Its recruitment into stress granules occurs in the absence
CC of TIAR proteins (By similarity). {ECO:0000250}.
CC -!- DOMAIN: Both the RRM domain and the arginine, glycine (RGG) rich domain
CC are necessary for binding to the TXN 3'-untranslated region. Both the
CC RRM domain and the arginine, glycine (RGG) rich domain (RGG repeats)
CC are necessary for optimal recruitment into SGs upon cellular stress.
CC The C-terminal domain containing RGG repeats is necessary for
CC translational repression (By similarity). {ECO:0000250}.
CC -!- PTM: Methylated on arginine residues. Methylation of the RGG motifs is
CC a prerequisite for recruitment into SGs (By similarity). {ECO:0000250}.
CC -!- PTM: Phosphorylated by CK2, GSK3A and GSK3B. Phosphorylation by GSK3B
CC increases RNA-binding activity to the TXN 3'-UTR transcript upon
CC exposure to UV radiation (By similarity). {ECO:0000250}.
