3 unusual facts about G protein


Krzysztof Palczewski

His work with determining the crystal structure of rhodopsin has given new insight into the function of G protein receptors.

Menelas N. Pangalos

Dr. Pangalos has edited the book “Understanding G protein-coupled receptors in the CNS”, as well as a number of journal issues focused on drug discovery in the CNS.

Rac3

Rac3 (Ras-related C3 botulinum toxin substrate 3) is a small (~21 kDa) monomeric GTP-binding protein G protein and is an important component of intracellular signalling pathways.


Estrogen receptor

In addition, some ER may associate with cell membranes by attachment to caveolin-1 and form complexes with G proteins, striatin, receptor tyrosine kinases (e.g., EGFR and IGF-1), and non-receptor tyrosine kinases (e.g., Src).

Pamoic acid

It was demonstrated that pamoic acid has agonist activity for the orphan G protein-coupled receptor GPR35 by which it activates ERK and beta-arrestin2, and causes antinociceptive activity.

Cetuximab

The KRAS gene encodes a small G protein on the EGFR pathway.

Complement component 5a

The latter interaction leads to receptor activation, and the transduction of the ligand binding signal across the cell plasma membrane to the cytoplasmic G protein GNAI2.

EBI2

G-protein coupled receptor 183 (GPR183), also known as Epstein-Barr virus-induced G-protein coupled receptor 2 (EBI2)

NOS1AP

This protein has a C-terminal PDZ-binding domain that mediates interactions with nNOS and an N-terminal phosphotyrosine binding (PTB) domain that binds to the small monomeric G protein, Dexras1.

Retinal G protein coupled receptor

Retinal G protein coupled receptor has been shown to interact with KIAA1279.
