Cell Biol. 19:94-105(2017). CC -!- FUNCTION: Sequence-specific RNA-binding protein that binds to the CC cytoplasmic polyadenylation element (CPE), an uridine-rich CC sequence element (consensus sequence 5'-UUUUUAU-3') within the CC mRNA 3'-UTR (PubMed:17024188). RNA binding results in a clear CC conformational change analogous to the Venus fly trap mechanism CC (By similarity). Regulates activation of unfolded protein response CC (UPR) in the process of adaptation to ER stress in liver, by CC maintaining translation of CPE-regulated mRNAs in conditions in CC which global protein synthesis is inhibited (PubMed:28092655). CC Required for cell cycle progression, specifically for cytokinesis CC and chromosomal segregation (By similarity). Plays a role as an CC oncogene promoting tumor growth and progression by positively CC regulating translation of t-plasminogen activator/PLAT CC (PubMed:22138752). Stimulates proliferation of melanocytes (By CC similarity). In contrast to CPEB1 and CPEB3, does not play role in CC synaptic plasticity, learning and memory (PubMed:24386439).

CC Expressed in spinal cord (at protein level) (PubMed:27381259). CC Expressed in kidney, lung and heart (at protein level) CC (PubMed:12871996, PubMed:27381259, PubMed:24386439).

CC -!- DEVELOPMENTAL STAGE: Highly expressed in developing brain, spinal CC cord and attached dorsal root ganglia (DRG) (at protein level). At CC embryonic day 18.5 expressed in gray matter of spinal cord, CC diencephalons, hippocampus and parts of midbrain and hindbrain. At CC postnatal day 20 expression persists in spinal cord and brain. CC Expressed in embryonic heart. {ECO:0000269|PubMed:27381259}. CC -!- INDUCTION: Up-regulated in granular cells of the dentate gyrus of CC CA1 and CA3 after kainate-induced seizures (PubMed:12871996). Up- CC regulated by high-fat-diet and aging-induced endoplasmic reticulum CC stress (PubMed:28092655). Expression level fluctuation follows the CC circadian clock amplitude (PubMed:28092655). CC {ECO:0000269|PubMed:12871996, ECO:0000269|PubMed:28092655}. CC -!- DOMAIN: The 2 RRM domains and the C-terminal region mediate CC interaction with CPE-containing RNA. The interdomain linker (564- CC 579) acts as a hinge to fix the relative orientation of the 2 CC RRMs. The ZZ domain (509-566) coordinates 2 Zn ions and is CC probably implicated in mediating interactions with other proteins CC in addition to increasing the affinity of the RRMs for the CPEs. CC Unlike in CPEB1, a continuous polar interface is formed between CC the 2 RRMs. {ECO:0000250|UniProtKB:Q17RY0, CC ECO:0000250|UniProtKB:Q9BZB8}. CC -!- DISRUPTION PHENOTYPE: No visible phenotype at young age or under CC unchallenged conditions (PubMed:24386439, PubMed:28092655). At 80 CC weeks or under high fat diet feeding conditions, mutant mice CC develop hepatosteatosis with excessive liver weight and CC accumulation of cytosolic lipid droplets sometimes accompanied by CC fibrosis (PubMed:28092655). {ECO:0000269|PubMed:24386439, CC ECO:0000269|PubMed:28092655}. CC -!- SIMILARITY: Belongs to the RRM CPEB family. {ECO:0000305}.
