Cloning and characterization of a novel isoform of calpastatin in human adult testis

Acta Pharmacol Sin. 2002 May;23(5):450-4.

Abstract

Aim: To clone a new gene related to human spermatogenesis.

Methods: cDNA probes of embryo and adult testis were used to hybridize the cDNA microarray of adult testis, and the clones of differential hybridization were sequenced and analyzed.

Results: A novel isoform of calpastatin exclusively and highly expressed in human adult testis was found.

Conclusion: A novel isoform of calpastatin expresses in human testis and it is related to spermatogenesis.
