Summary
This gene belongs to the VCX/Y gene family, which has multiple members on both X and Y chromosomes, and all are expressed exclusively in male germ cells. The X-linked members are clustered on chromosome Xp22, and the Y-linked members are two identical copies of the gene within a palindromic region on chromosome Yq11. The family members share a high degree of sequence identity, with the exception that a 30-nt unit is tandemly repeated in X-linked members but occurs only once in Y-linked members. The VCX gene cluster is polymorphic in terms of copy number; different individuals may have a different number of VCX genes. This family member, as represented by the reference genome allele, contains 14 copies of the 30-nt repeat unit. VCX/Y genes encode small and highly charged proteins containing putative bipartite nuclear localization signals. Although the exact function of this family member has yet to be determined, a role in mRNA stability regulation can be inferred from the ability of the highly similar family member, VCX-A, to inhibit mRNA decapping. A possible role in the regulation of ribosome assembly during spermatogenesis has also been suggested. [provided by RefSeq, Aug 2010]

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.
