Protein phosphorylation is commonly involved with all of the following except
a. activation of receptor tyrosine kinases.
b. activation of protein kinase molecules.
c. activation of g protein-coupled receptors.
d. regulation of transcription by signaling molecules.

Protein phosphorylation is not involved in activation of G protein coupled receptor.

Further Explanation:

Roles of Protein phosphorylation are :

G- protein coupled receptor is activated through the external signals in the forms of ligand.

In this, ligand binds to the active site and cause conformation changes in receptor and active G- protein.
