Calmodulin-dependent protein phosphatase, calcineurin, is involved in a wide range of biologic activities, acting as a Ca(2+)-dependent modifier of phosphorylation status. In testis, the motility of the sperm is thought to be controlled by cAMP-dependent phosphorylation and a unique form of calcineurin appears to be associated with the flagellum. The calcineurin holoenzyme is composed of catalytic and regulatory subunits of 60 and 18 kD, respectively. At least 3 genes, calcineurin A-alpha, calcineurin A-beta, and calcineurin A-gamma, have been cloned for the catalytic subunit. These genes have been identified in humans, mice, and rats, and are highly conserved between species (90 to 95% amino acid identity).

Titration of the PPP3CC antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A portion of amino acids 482-512 from the human protein was used as the immunogen for this PPP3CC antibody.

Aliquot the PPP3CC antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
