What Does PK Stand For?

PK stands for Protein Kinase

Protein Kinase (PK) refers to a family of enzymes that play a crucial role in cellular signaling by catalyzing the transfer of phosphate groups from high-energy molecules, such as ATP, to specific substrates, typically proteins. This phosphorylation process modifies the activity, localization, or stability of the target proteins, thereby regulating various physiological processes including cell growth, differentiation, and metabolism. PKs are integral to numerous signaling pathways and have significant implications in health and disease, making them important targets for therapeutic intervention.
