G coupled protein receptors (GCPR) are one of the largest families of receptors and mediate a variety of biological responses. Rhodopsin is the largest family and aids in sight, the α-subunit of the GCPR complex in extremely important to the activation and downstream signaling effects of GCPR. The α-subunit contains a small trans-domain portion and in this project the sequence of that portion will be inserted into a vector containing a fluorescent tag. These vectors will then be used to collect fluorescent cross correlation spectroscopy or FCCS data. The unit was cloned using assembly methods that include PCR and purification …

G protein coupled receptors (GPCRs) are membrane proteins with many functional roles. This family of receptors is expansive, with several subfamilies. Here, a member of subfamily A, rhodopsin (Rho) is studied. Mutations in rhodopsin have been linked to the disease retinitis pigmentosa (RP). Some of these mutations have been found to disrupt the dimerization/oligomerization of Rho at the TM4/TM5 proposed dimerization interface, causing pathogenesis of RP. In this study, two mutations of transmembrane helix 5 were investigated for changes in dimerization and stability, cell trafficking, and signaling. It was found that the V209M and F220C mutations did not result in …
