S Kinase, also known as Serine Kinase, is an essential enzyme involved in several cellular processes. This type of kinase plays a crucial role in signal transduction pathways, regulating numerous intracellular events. Synonyms for S Kinase include Serine/Threonine Kinase and Peptide Kinase. These terms refer to the same type of enzyme that phosphorylates serine and/or threonine amino acids on proteins. Various serine kinases exist within cells, each with specific functions and targets. Understanding these synonyms is crucial in comprehending the vital role that S Kinase plays in cellular signaling and its impact on cellular physiology and disease processes.
