Seminalplasmin and caltrin are the same protein

AbstractThe sequence of seminalplasmin, a basic antimicrobial and transcription-inhibitory protein from bovine seminal plasma, has been determined using an automated sequenator. This sequence is slightly different from that reported earlier by Theil and Scheit [(1983) EMBO J. 2, 1159-1163] and identical with that of caltrin, a Ca2+-transport-inhibitory protein of bovine seminal plasma. Caltrin and seminalplasmin are, therefore, the same protein.SeminalplasminCaltrinSeminal plasma protei
