Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Context:

  • G protein-binding receptors share conserved structural features, including seven transmembrane segments and sequence homologies.
  • These similarities provide a basis for developing universal cloning strategies.

Purpose:

  • To describe a polymerase chain reaction (PCR)-based method for cloning G protein-binding receptors.
  • To detail the isolation and sequencing of the thyrotropin (TSH) receptor.
  • To outline strategies for identifying the functions of newly sequenced receptors with unknown natural ligands.

Summary:

  • A polymerase chain reaction (PCR) method was developed to clone G protein-binding receptors by exploiting their conserved structural similarities.
  • This technique enabled the sequencing of numerous hormone receptors, including the thyrotropin (TSH) receptor, offering new insights into autoimmune thyroid diseases.
