A protein is targeted to the plasma membrane.Its final functional location is as a subunit of a transmembrane protein that interacts with the central subdomain of the membrane.Analysis of this protein would most likely show modification with a
A) myristoylate.
B) palmitoylate.
C) isoprenoid.
D) phosphate.

Question

Quizplus · Accepted Answer

Palmitoylation is the attachment of a fatty acid (palmitate) to the cysteine residue of a protein. This modification is commonly found in proteins that are associated with the plasma membrane and is important for anchoring the protein to the membrane. Therefore, the protein in question is likely palmitoylated.
