Cytoplasmic polyadenylation element-binding protein 3 (CPEB3)

Sequence-specific RNA-binding protein which functions as a translational repressor from the basal unstimulated state however, following adrenal stimulation, functions as a translational activator (By similarity). Compared to CPEB1, does not bind to the cytoplasmic polyadenylation element (CPE), a uridine-rich sequence element within the mRNA 3'-UTR, but binds to a U-rich loop within a stem-loop structure (By similarity).

Required for the consolidation and maintenance of hippocampal-based long term memory (By similarity). Also represses the translation of DLG4, GRIN1, GRIN2A and GRIN2B (By similarity).
