Question

Quizplus · Accepted Answer

The function of a protein kinase is to add phosphate groups onto proteins in a process called phosphorylation. This protein modification is important for regulating cellular processes such as metabolism, signal transduction, and gene expression. The addition of a phosphate group can activate or deactivate a protein, change its location within the cell, or alter how it interacts with other proteins.
