Which of the following mechanisms is not directly involved in inactivating an activated RTK?
A) digestion of the RTK in lysosomes
B) dephosphorylation by serine/threonine phosphatases
C) dephosphorylation by protein tyrosine phosphatases
D) removal of the RTK from the plas ma membrane by endocytosis

Respuesta :

The mechanism that is not directly involved in  inactivating an activated RTK is A) digestion of the RTK in lysosomes.

In the field of biology, receptor tyrosine kinase can be described as proteins present on cell membrane receptors that help in cell signaling.

In order to activate the RTK, phosphorylation of the RTK is done through phosphateses such as serine, threonine and tyrosine.

In order to inactivate the RTK, dephosphorylation is dine by the serine, threonine and tyrosine. Deactivation can also be done by removing thr RTK from the plasma memebrane through the process of endocytosis.
