Question

Q.47. An example of a receptor which is a structural protein,
a) Na/K ATPase
b) acetylcholinesterase
c) tubulin
d) DNA
e) phospholipase C​

Answer 1

Answer:

d answer is the correct

Answer 2

Answer:

c) Tubulin is the correct answer.

Explanation:

Tubulin:

• Eukaryotic cells rely on α- and β-tubulin, polymerized into microtubules, for structural support, intracellular support, and DNA segregation.
• Tubulin, a globular protein, has inflexible hollow, fibrous shafts that measure roughly 25 nm in diameter that make up these structures.
• Tubulin increases G protein activation that is independent of receptors.
• Tubulin GTPase is promoted by heterotrimeric G proteins, which increases microtubule dynamics. GPCR activation changes cell shape by releasing G and G from the plasma membrane.
