The effects of protein kinase A catalytic subunit on sperm motility regulation in Pacific abalone Haliotis discus hannai

Protein kinase A plays a central role in the regulation of sperm motility from echinoderms to mammals, but the information about its regulatory role in molluscs is very limited. In this study, a protein kinase A catalytic subunit (designated as HdPKA-C) was identified from Pacific abalone Haliotis discus hannai. The open reading frame of HdPKA-C was of 1,077 bp, encoding a peptide of 358 amino acids with a typical protein kinase domain. HdPKA-C...
