Methods Recombination pcDNA3/HBRP was constructed and transfected to HEK293 cell and permanently expression cell line was established. The activity of protein kinase C （PKC） of the cell line was detected by autoradiography method. Results The stable expression cell line of HBRP was obtained. The HBRP inhibited the activity of PKC significantly. Conclusion One of the new functions of novel sperm binding protein in human is the inhibitor action on activity of PKC. It may be involved in the sperm capacitation and acrosome reaction.展开更多
