MAPK12, also known as ERK3, ERK6, P38GAMMA, PRKM12, SAPK-3, or SAPK3, belongs to the essential family of Mitogen-Activated Protein Kinases (MAPKs). is involved in intracellular signaling cascades that respond to various stimuli. Upon activation, it phosphorylates downstream targets, modulating their activity and ultimately affecting cellular processes.
