Question

Below is the molecular structure of a single bovine  -arrestin subunit.Two locations are indicated.What is most likely to interact with the protein at these locations? 
A) ARK 
B) GTP-bound 
C) dephosphorylated GPCR 
D) phosphorylated GPCR

Quizplus · Accepted Answer

The two locations indicated on the molecular structure are potential binding sites for phosphorylated G protein-coupled receptor (GPCR). Therefore, the best choice is D, phosphorylated GPCR.
