Summary: 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]

Data demonstrated an increased occurrence of both SRSF3 and the CPEB2B isoform in triple negative breast cancer (TNBC), and identified a consensus binding motif for SRSF3 in the exon promoting the CPEB2B isoform. The study also suggests that the splicing event, which promotes the expression of CPEB2B, is driven by SRSF3 as well as linked to aggressive growth in metastatic TNBC.

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.
