The following class of receptors either associates with a kinase or has a kinase domain:
a. enzyme coupled receptors
b. G protein coupled receptor
c. nuclear receptor
d. ion channel coupled receptor
Homework Answers
Solution - Correct answer is GPCR. G protein coupled receptor is a major type of cell signalling receptor , which includes a kinase domain in its C terminal. When the ligand bind to the receptor in GPCR the kinase domain phosphorylates G-Protein which then moves the effector molecule.
