The evolution of gonadotropins: some molecular data concerning a non-mammalian pituitary gonadotropin, the hormone from a teleost fish (Cyprinus carpio L.).
The amino acid and sugar compositions as well as long N-terminal sequences and the C-terminal amino acids of the two subunits of carp gonadotropin, SU I and SU II, were determined. An important homology was demonstrated between SU I and alpha-subunits and between SU II and beta-subunits of mammalian gonadotropins. Moreover SU II was more closely related to the beta-subunit of LH than to the beta-subunit of FSH.
