Summaries for CPEB2 Gene

Entrez Gene Summary for CPEB2 Gene

  • The protein encoded by this gene is highly similar to cytoplasmic polyadenylation element binding protein (CPEB), an mRNA-binding protein that regulates cytoplasmic polyadenylation of mRNA as a trans factor in oogenesis and spermatogenesis. Studies of the similar gene in mice suggested a possible role of this protein in transcriptionally inactive haploid spermatids. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for CPEB2 Gene

CPEB2 (Cytoplasmic Polyadenylation Element Binding Protein 2) is a Protein Coding gene. Among its related pathways are Oocyte meiosis. Gene Ontology (GO) annotations related to this gene include nucleic acid binding and nucleotide binding. An important paralog of this gene is CPEB4.

UniProtKB/Swiss-Prot for CPEB2 Gene

  • May play a role in translational regulation of stored mRNAs in transcriptionally inactive haploid spermatids. Binds to poly(U) RNA oligomers (By similarity). Required for cell cycle progression, specifically for the transition from metaphase to anaphase (PubMed:26398195).
