A protamine, which has been named stellin, has been isolated from the mass of sperm of the sevruga(Acipenser stellatus).

Stellin is heterogeneous and consists of a mixture of peptides differing in amino acid composition and in chain length. There is great similarity between stellin and sturin both with respect to amino acid composition and with respect to N-terminal amino acids.
