Semenogelin, the predominant protein in human semen. Primary structure and identification of closely related proteins in the male accessory sex glands and on the spermatozoa
The predominant protein in human semen, semenogelin, was characterized by lambda gt11 clones isolated from a seminal vesicular cDNA library. One clone, carrying a cDNA insert of 1606 nucleotides and a polyadenylated tail, coded for the entire semenogelin precursor. An open reading frame of 1386 nucleotides encodes a signal peptide and the mature protein of 439 amino acid residues, in which residue
