Cloning and sequencing of human FSH receptor cDNA.

We have isolated and sequenced a cDNA encoding the follicle stimulating hormone (FSH) receptor. The deduced amino acid sequence (678 residues) containing seven putative transmembrane segments which displays sequence similarity to G protein-coupled receptors. The receptor consists of 359 residue extracellular domain which contains four N-linked glycosylation sites. While the protein is 89% identical overall with the previously cloned rat FSH receptor, the most highly conserved regions are the putative transmembrane segments (95% similarity).
