Nucleic acid and protein sequences relating to a cation channel which is sperm-specific (CatSper2) are disclosed. The CatSper2 protein is shown to be specifically expressed in sperm. Nucleic acids, vectors, transformed cells, transgenic animals, polypeptides, and antibodies relating to the CatSper2 gene and protein are disclosed. Also provided are methods of in vitro fertilization and contraception, methods of identifying modulators of CatSper2 activity, methods of genotyping subjects with respect to CatSper2, methods of diagnosing and treating CatSper2-mediated disorders, including infertility, as well as methods of doing business related to CatSper2-mediated disorders.

The present invention relates to a functionally expressed bacterial voltage-sensitive ion-selective channel. The novel channel can be used in conjunction with mammalian ion channel pore-containing regions in assays for screening for compounds that modulate activity of the channel. One bacterial ion channel of the present invention, called NaChBac, is derived from(GenBank#BAB05220 (8)).
