Summary: Enables nucleic acid binding activity and ribosome binding activity. Involved in cellular response to hypoxia; negative regulation of cytoplasmic translation; and regulation of translation at synapse, modulating synaptic transmission. Acts upstream of or within negative regulation of translational elongation. Located in cytoplasm and ribosome. Is active in glutamatergic synapse. Is expressed in central nervous system; early conceptus; and olfactory epithelium. Orthologous to human CPEB2 (cytoplasmic polyadenylation element binding protein 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
