- * Seminal vesicle protein II repeats signature *
- ************************************************
-
- Seminal vesicle protein II (SVP-II) [1] is one of the six major secretory
- proteins secreted by rat seminal vesicle. It is a clotting protein that serves
- as the substrate in the formation of the copulatory plug. Covalent clotting
- of this protein is catalyzed by a transglutaminase and involves the formation
- of gamma-glutamyl-epsilon-lysine crosslinks. SVS-II sequence contains thirteen
- repeats of a thirteen amino acid residue domain which is probably involved in
- the cross-linking. There are a number of invariant residues in this domain,
- four of them (two lysines and two glutamines) probably participate in the
- cross-links. The pattern we have developed comprises positions 2 to 12 of the
- domain and includes the four putative cross-linking residues.
-
- -Consensus pattern: [GSA]-Q-x-K-S-[FY]-x-Q-x-K-[SA]
- [Q's and K's are probably involved in cross-links]
- -Sequences known to belong to this class detected by the pattern: ALL; it will
- detect 12 of the 13 occurrences of the repeat.
- -Other sequence(s) detected in SWISS-PROT: NONE.
