[Current data on the structure-activity relationship of gonadotropins]

Area of Science:

• Endocrinology
• Molecular Biology
• Biochemistry

Context:

• Gonadotropins are crucial glycoprotein hormones regulating reproductive functions.
• Recent years have seen significant progress in understanding gonadotropin structure and receptor interactions.
• Availability of purified hormones, recombinant counterparts, and cloned receptors facilitates structure-activity relationship studies.

Purpose:

• To review the current understanding of gonadotropin structure, heterogeneity, and receptor interactions.
• To highlight advances in studying gonadotropin structure-activity relationships using modern biotechnologies.
• To identify areas requiring further research, particularly in determining the 3D structure of gonadotropins.

Summary:

• This review covers the alpha and beta subunit structure of glycoprotein hormones (gonadotropins).
• It discusses hormonal heterogeneities (carbohydrate, peptide) influencing bioactivity and immunoreactivity.
• The review details G-protein coupled receptor structures and functional domains, and hormone-receptor interaction regions.

Impact:

• Provides critical information for developing therapies for reproductive disorders and fertility control strategies.
• Advances knowledge on structure-activity relationships, aiding in the design of new analogs.
• Identifies the need for 3D structure determination for improved understanding of endocrinological diseases and therapeutic design.
