[Cloning and sequence of thyrotropin beta subunit of a teleost fish: the eel (Anguilla anguilla L.)].
We obtained the sequence of eel thyrotropin beta-subunit cDNA. About 1,100 bp long, it encodes a 147-amino acid protein including a 20-residue signal peptide. We analyse homologies between angTSH beta and the other known beta-subunits taking in account the ability of mammal gonadotropins (GTH) to stimulate teleost thyroid. A peptide corresponding to mammalian CAGYC (implicated in subunit association) is original and different from its eel beta GTH2 counterpart.
