Title : Primary structure of a new actin-binding
protein from human seminal plasma
Abstract :
- Secretory actin-binding protein ( SABP ), a glycoprotein from human seminal plasma, was isolated according to Akiyama and Kimura [Akiyama, K. & Kimura, H. (1990) Biochim
- Biophys
- Acta 1040, 206-210]
- The complete amino acid sequence of SABP was determined with the aid of fragments generated by trypsin, Staphylococcus aureus V8 protease and pepsin
- The single polypeptide chain of SABP contains 118 amino acids with a calculated Mr of 13,506 and pyroglutamic acid as the N-terminal residue
- A single N-glycosidic carbohydrate moiety is located at Asn77
- The carbohydrate composition shows an unusually high amount of fucose
- The arrangement of the two disulfide bonds is Cys37-Cys63 and Cys61-Cys95
- Sequence comparison revealed a high degree of similarity with a 14-kDa submandibular gland protein from mouse (45% identity and 64% similarity)
- SABP is identical with a prolactin-inducible protein and a protein termed gross cystic disease fluid protein 15 ( sequences translated from cDNA clones), both from human breast tissues
- Although SABP was also detected in saliva, in extracts of the submandibular gland and seminal vesicles, little is known of its function
