表达:
Q14011 CIRBP_HUMAN:

Ubiquitous.

描述:
Cold-inducible mRNA binding protein that plays a protective role in the genotoxic stress response by stabilizing transcripts of genes involved in cell survival. Acts as a translational activator. Seems to play an essential role in cold-induced suppression of cell proliferation. Binds specifically to the 3'-untranslated regions (3'-UTRs) of stress-responsive transcripts RPA2 and TXN. Acts as a translational repressor (By similarity). Promotes assembly of stress granules (SGs), when overexpressed.

研究背景

功能:

Cold-inducible mRNA binding protein that plays a protective role in the genotoxic stress response by stabilizing transcripts of genes involved in cell survival. Acts as a translational activator. Seems to play an essential role in cold-induced suppression of cell proliferation. Binds specifically to the 3'-untranslated regions (3'-UTRs) of stress-responsive transcripts RPA2 and TXN. Acts as a translational repressor (By similarity). Promotes assembly of stress granules (SGs), when overexpressed.

翻译修饰:

Methylated on arginine residues. Methylation of the RGG motifs is a prerequisite for recruitment into SGs (By similarity).

Phosphorylated by CK2, GSK3A and GSK3B. Phosphorylation by GSK3B increases RNA-binding activity to the TXN 3'-UTR transcript upon exposure to UV radiation.

细胞定位:

Nucleus>Nucleoplasm. Cytoplasm.
Note: Translocates from the nucleus to the cytoplasm after exposure to UV radiation. Translocates from the nucleus to the cytoplasm into stress granules upon various cytoplasmic stresses, such as osmotic and heat shocks. Its recruitment into stress granules occurs in the absence of TIAR proteins (By similarity).

组织特异性:

Ubiquitous.

亚基结构:

Interacts with EIF4G1. Associates with ribosomes.

蛋白家族:

Both the RRM domain and the arginine, glycine (RGG) rich domain are necessary for binding to the TXN 3'-untranslated region. Both the RRM domain and the arginine, glycine (RGG) rich domain (RGG repeats) are necessary for optimal recruitment into SGs upon cellular stress. The C-terminal domain containing RGG repeats is necessary for translational repression (By similarity).

Application: WB    Species: Mouse    Sample:

Figure 6 CD4+ T cells were assessed for the expression of mTOR pathway-associated proteins, ERS-associated proteins, and apoptosis-associated proteins in WT, LCK-mTOR, LCK-TSC1, CLP, CLP+CIRP-Ab, CLP+NAC, LCK-TSC1+CLP, and Lck-mTOR+CLP mouse groups. Data are mean ± SD. Number of mice per group = 4 (one-way ANOVA Tukey's post hoc test). CD4+ T cells were purified from CIRP-Ab-treated mice, NAC-treated mice, TSC1 knockout mice, and mTOR mouse spleen lymphocytes. Total proteins were western blotted to identify the expression patterns of mTOR pathway proteins (P-mTOR, mTOR, p70s6k, p-p70s6k, P-4EBP, and 4EBP) (a); CIRP and ERS-associated proteins (GRP78 and CHOP) (b); and apoptosis-related proteins (caspase-3, Bax, and Bcl-2) (c).
