cytoplasmic polyadenylation element binding protein 1. Binds to the protein CPE and drives its polyadenylation. Activated by the protein kinase AurA. Insulin and progesterone stimulate AurA-catalyzed phosphorylation of CPEB in oocytes. Neuronal CPEB regulates local protein synthesis and stabilizes synapse-specific long-term facilitation in aplysia. Note: This description may include information from UniProtKB.
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
