**Background of STK24 Recombinant Protein**
STK24 (serine/threonine kinase 24), also known as MST3 (mammalian STE20-like protein kinase 3), is a member of the STE20 family of protein kinases. It plays a critical role in regulating diverse cellular processes, including apoptosis, cell proliferation, polarity, and stress responses. Structurally, STK24 contains an N-terminal kinase domain responsible for catalytic activity and a C-terminal regulatory domain that facilitates interactions with scaffolding proteins or signaling complexes. This kinase is part of the STRIPAK (striatin-interacting phosphatase and kinase) complex, which modulates its activity through phosphorylation-dependent signaling pathways.
The recombinant STK24 protein is produced using genetic engineering techniques, typically expressed in bacterial (e.g., *E. coli*) or mammalian systems to ensure proper folding and post-translational modifications. Purified STK24 recombinant protein retains enzymatic activity and is widely used in *in vitro* studies to investigate its substrate specificity, regulatory mechanisms, and interactions with binding partners. Researchers employ techniques like kinase assays, co-immunoprecipitation, and structural analysis (e.g., X-ray crystallography) to explore its functional roles.
STK24 has been implicated in diseases such as cancer, neurological disorders, and immune dysregulation. For example, it acts as a tumor suppressor in certain contexts by inhibiting pro-survival signals, while its dysregulation is linked to neurodegenerative conditions like Alzheimer’s disease. Recombinant STK24 enables drug discovery efforts, serving as a target for screening small-molecule inhibitors or activators to modulate its activity therapeutically.
Overall, STK24 recombinant protein is a vital tool for deciphering the molecular basis of cellular signaling and developing strategies to target kinase-mediated pathways in disease.
