Cysteine 21-29 protamine 1 Mus musculus 39-50 3840106-1 1985 We utilized a cDNA encoding the cysteine-rich, tyrosine-containing mouse protamine, mouse protamine 1 (MP1), to detect the presence of several classes of differentiating germ cells in testicular extracts from wild-type and male sterile mutant mice. Cysteine 32-40 protamine 1 Mus musculus 90-101
