Quantification Of Hfshr Signaling To Determine Lipid Raft Residency, Gregory Geisel

Honors Theses

Human follicle stimulating hormone (hFSH) is a gonadotropin responsible for regulating reproductive systems by stimulation of Sertoli cells in males and granulosa cells in females. The hFSH receptor (hFSHR) is a seven transmembrane receptor that belongs to the G protein coupled receptor family. The receptor is functionally connected to a G protein on the inside of the cell. Once FSH activates its receptor, a cascade of signaling begins, resulting in the activation of adenylyl cyclase, which increases the intracellular levels of cAMP. In addition, hFSHR stimulation also activates the p44/42 MAP kinase. The spike in cAMP activates the enzyme protein …
