The invention provides recombinant native and mutein forms of human follicle stimulating hormone beta subunit (FSH beta) with characteristic glycosylation patterns which are influential in the metabolic activity of the protein. The invention also provides recombinant mutant forms of the human alpha subunit common to FSH, LH, CG, and TSH, to obtain hormones which also have unique glycosylation patterns. Also provided are recombinant materials to produce these subunits separately or together to obtain complete heterodimeric hormones of regulated glycosylation pattern.

Follicle stimulating hormone-glycosylation analogs

Recombinant materials are provided for the production of the &agr;-glycoprotein hormone subunit. These muteins have utility as antagonists and in altering pharmacokinetic activity of these hormones.

Modified protein pharmaceuticals extended with a CTP unit retain their biological activity and they had extended biological half-lives. The CTP extension represents an amino acid sequence derived from that of positions 112-118 to 145 of human chorionic gonadotropin.
