| Function | 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 3'-UTR of mRNAs. 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 (By similarity). 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 (By similarity). {ECO:0000250}. |
| Subcellular Location | Cytoplasm {ECO:0000250}. Cell junction, synapse {ECO:0000250}. Cytoplasm, P-body {ECO:0000250}. Cytoplasmic granule {ECO:0000250}. Membrane {ECO:0000250}. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density {ECO:0000250}. Note=Localizes in synaptosomes at dendritic synapses of neurons. Strongly enriched in postsynaptic density (PSD) fractions. Transported into dendrites in a microtubule- dependent fashion and colocalizes in mRNA-containing particles with TACC3, dynein and kinesin. Membrane-associated. Colocalizes at excitatory synapses with members of the polyadenylation and translation complex factors (CPSF, APLP1, TACC3, AURKA, SYP, etc.) including CPE-containing RNAs. In P-bodies and stress granules (By similarity). Recruited to stress granules (SGs) upon arsenite treatment (By similarity). {ECO:0000250}. |
| Tissue Specificity | Expressed in hippocampus, cerebral cortex and oocytes (at protein level). Expressed in brain, heart, kidney, lung and ovary and testis. Weakly expressed in granular cells of dentate gyrus and the pyramidal cells of CA3 and CA1 of the hippocampus. {ECO:0000269|PubMed:11526086, ECO:0000269|PubMed:11980711, ECO:0000269|PubMed:12871996, ECO:0000269|PubMed:8962099, ECO:0000269|PubMed:9856468}. |
