摘要：

In our previous studies (Fujinoki et al., 2001, 2003), we reported that two types of 36 kDa proteins, designated 36K-A protein and 36K-B protein, obtained from hamster sperm flagella, are associated with motility activation and phosphorylated in a cAMP-dependent manner at serine residues. In the present experiments, we focused on the hamster (Mesocricetus auratus) 36K-A protein, which was analyzed by peptide mass finger printing and amino acid sequencing. The results suggest that 36K-A protein is a pyruvate dehydrogenase E1 component beta subunit lacking the N-terminal 30 amino acids. Moreover, our results suggest that 36 K-A protein is localized in the fibrous sheath of the principal piece of hamster spermatazoa. (C) 2004 Elsevier Inc. All rights reserved.
