Which of the following is a characteristic of Hsp90 chaperones?
A)They comprise more than 20% of total cytosolic proteins in eukaryotes.
B)Their action depends on cyclic binding and hydrolysis of GTP.
C)They direct proteins toward degradation pathways.
D)Their major purpose is conformational regulation of signal transduction molecules.

Question

Quizplus · Accepted Answer

Hsp90 chaperones primarily function in conformational regulation of signal transduction molecules, helping them adopt their active conformation. They do not comprise 20% of total cytosolic proteins, do not rely on cyclic binding and hydrolysis of GTP, and do not direct proteins toward degradation pathways.
