Caveolin Binding Motif Mutation Yields A Variance In Follicle Stimulating Hormone Receptor Signaling, Justin Fleischer

Honors Theses

The human follicle stimulating hormone receptor (hFSHR) is a glycoprotein hormone receptor belonging to the g protein-coupled receptor family. It is important in both male and female reproductive processes; defects in hFSHR can lead to infertility, delayed puberty, reduced muscle bulk, and osteoporosis. Work in other labs has shown that GPCRs can be localized to microdomains located within the cell membrane called lipid rafts. These regions are highly resistant to detergents because of the high concentration of sphingolipids and cholesterol. Also within these domains, an intracellular protein, caveolin, is present. Our lab has shown that hFSHR also localizes to lipid …
