**Background of STK38L Recombinant Protein**
STK38L (Serine/Threonine Kinase 38 Like), also known as NDR2 or CIT-2. is a member of the NDR (Nuclear Dbf2-related) kinase family within the broader AGC (PKA/PKG/PKC) kinase superfamily. This evolutionarily conserved kinase plays critical roles in regulating cellular processes such as cell cycle progression, apoptosis, and morphological changes. Structurally, STK38L contains an N-terminal regulatory domain and a C-terminal catalytic kinase domain. Its activation typically requires phosphorylation by upstream kinases, such as MST1/2 (components of the Hippo pathway), and binding to regulatory proteins like MOB1.
STK38L is implicated in diverse biological functions, including cell proliferation, differentiation, and polarity maintenance. Studies link it to neurodevelopment, tumor suppression, and immune responses. For instance, STK38L interacts with the Hippo signaling pathway to control organ size and tissue homeostasis, while its dysregulation has been observed in cancers (e.g., breast cancer, gliomas) and neurodegenerative disorders. In neurons, STK38L modulates dendritic growth and synaptic plasticity, potentially influencing cognitive functions.
Recombinant STK38L protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains enzymatic activity and is widely used to study its kinase mechanisms, substrate specificity, and interactions. Purified through affinity chromatography and validated via functional assays (e.g., in vitro kinase assays), this tool enables exploration of STK38L's role in signaling networks and disease contexts. Researchers also leverage recombinant STK38L for drug discovery, aiming to target its activity in pathological conditions like cancer or neurological disorders.
Overall, STK38L recombinant protein serves as a vital resource for deciphering the kinase's biological significance and therapeutic potential.
