Which protein binds PKA to the cytoskeleton ?
A kinase anchoring protein (AKAP)
Full form of GPCR
G proteinn coupled receptor
Any one ligand for nuclear receptor
Steroid hormones, Thyroid hormones, Retinoid etc
What is the function of loops of GPCR on cytosolic side of plasma membrane?
Binding site for G protein/Arrestin
Give an example of enzyme that brings about phosphorylation
Kinases
How many times polypeptide of GPCR intervene plasma membrane ?
7
What is the function of GTPase-activating proteins?
(GAPs) drive the proteins into an “off” state by increasing the rate of hydrolysis of bound GTP.
