Protein-serine-threonine kinase

Molecular classification
Enzyme, Protein Kinase, Serine/Threonine Kinase
01

Overview

Protein-serine-threonine kinases are a large group of enzymes that catalyze the transfer of a phosphate group from ATP to serine or threonine residues in protein substrates. This post-translational modification regulates protein function and cellular signaling pathways, influencing activity, stability, localization, and interactions. They play fundamental roles in controlling cell growth, differentiation, metabolism, apoptosis, and synaptic plasticity. Dysregulation is implicated in diseases like cancer, neurodegeneration, and metabolic syndromes, making them major therapeutic targets.
