CATSPER2 - cation channel sperm associated 2 Gene

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 117155

About CATSPER2

Cytogenetic location: 15q15.3 Genomic coordinates (GRCh38): 15:43,628,503-43,648,884 (from NCBI)

This gene has 12 transcripts (splice variants), 141 orthologues, 26 paralogues and is associated with 3 phenotypes. Broad expression in testis (RPKM 13.6), skin (RPKM 2.9) and 15 other tissues.

Summary

This gene encodes a member of a family of cation channel proteins that localize to the flagellum of spermatozoa. Defects at this locus causes male infertility. Alternatively spliced transcript variants have been observed at this locus. Readthrough transcription originates upstream of this locus in diphosphoinositol pentakisphosphate kinase 1 pseudogene 1 and is represented by GeneID:110006325. Related pseudogenes are found next to this locus on chromosome 15 and on chromosome 5. [provided by RefSeq, Mar 2017]
