Summary
The protein encoded by this gene is found in the fibrous sheath of spermatazoa, where it interacts with rhophilin, a Rho GTPase binding protein. The encoded protein also can bind an A-kinase anchoring protein (AKAP110) and a calcium-binding tyrosine phosphorylation-regulated protein (CABYR). This protein may be involved in sperm motility and has been shown to be a cancer-testis antigen in hematologic malignancies. Several transcript variants, some protein-coding and some non-protein coding, have been found for this gene. [provided by RefSeq, Dec 2015]

  2. There is downregulation of both ROPN1 and CABYR in asthenozoospermic samples and importantly, a positive correlation between the expression of the two genes, suggesting that ROPN1 and CABYR co-expression is a prerequisite for normal flagellar function and sperm motility.

  3. Ropporin gene expression is related to the sperm motility. Its abnormal expression in the sperm of asthenozoospermic men with varicocele is associated with impaired sperm motility that is improved after varicocelectomy.

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.
