PRKG1 (Protein Kinase, cGMP-Dependent, Type I): PRKG1 is a gene that encodes a serine/threonine-specific protein kinase, serving as a key effector in cyclic guanosine monophosphate (cGMP) signaling. It plays a crucial role in regulating vascular smooth muscle tone, platelet function, and cardiac contractility, thereby supporting cardiovascular homeostasis. Through phosphorylation of target proteins, PRKG1 impacts processes such as smooth muscle relaxation, protection from myocardial injury, and inhibition of platelet aggregation; its activity is closely associated with cardiovascular health and disease.
