![45. Receptor tyrosine kinases (RTK)s are the high-affinity cell surface receptors for many
polypeptide growth factors, cytokines, and hormones. The following statements are about
receptor tyrosine kinases.
A. Receptor tyrosine kinases will undergo conformational changes upon binding of ligands, but
cannot move across cell membranes upon binding of ligands.
B. Receptor tyrosine kinases can bind certain protein phosphatases.
C. Receptor tyrosine kinases can only phosphorylate themselves (called autophosphorylation)
but do not phosphorylate other proteins/enzymes.
D. Receptor tyrosine kinases phosphorylate one or more specific tyrosine residues, but not all
tyrosine residues of a particular protein.
The correct statement(s) is(are):
a) only A andD
b) only B and C
c) only B and D
d) only A, B and D
e) All of them
