Evidence for PS localization
Functions
Sequence-specific RNA-binding protein that regulates mRNA cytoplasmic polyadenylation and translation initiation during oocyte maturation, early development and at postsynapse sites of neurons. Binds to the cytoplasmic polyadenylation element (CPE), an uridine-rich sequence element (consensus sequence 5-UUUUUAU-3) within the mRNA 3-UTR. RNA binding results in a clear conformational change analogous to the Venus fly trap mechanism (PubMed). In absence of phosphorylation and in association with TACC3 is also involved as a repressor of translation of CPE-containing mRNA; a repression that is relieved by phosphorylation or degradation . Involved in the transport of CPE-containing mRNA to dendrites; those mRNAs may be transported to dendrites in a translationally dormant form and translationally activated at synapses . Its interaction with APLP1 promotes local CPE-containing mRNA polyadenylation and translation activation . Induces the assembly of stress granules in the absence of stress. Required for cell cycle progression, specifically for prophase entry (PubMed). [View more on UniProt]
