Shk2

Shk2, also known as SIK2, is a serine/threonine kinase belonging to the AMP-activated protein kinase (AMPK) related kinase family. It is encoded by the SIK2 gene in humans. Shk2 plays a role in various cellular processes, including cellular metabolism, adipogenesis, and cell migration. It is activated by upstream kinases and, in turn, phosphorylates a range of target proteins, influencing their activity and localization. Research suggests Shk2 is involved in the regulation of glucose and lipid metabolism, potentially impacting energy homeostasis within the cell. Its role in adipogenesis indicates a function in the development and maintenance of fat tissue. Furthermore, Shk2 has been implicated in the migratory capacity of cells, which is relevant to processes such as wound healing and potentially cancer metastasis. The precise mechanisms and full spectrum of Shk2's functions are still under active investigation, with ongoing research aiming to elucidate its complete physiological and pathological roles.
