**Background of SGK3 Recombinant Protein**
Serum- and glucocorticoid-regulated kinase 3 (SGK3), a member of the serine/threonine kinase family, plays a critical role in cellular signaling pathways regulating cell survival, proliferation, and stress responses. It shares structural and functional similarities with SGK1 and SGK2 but exhibits distinct regulatory mechanisms and tissue expression patterns. SGK3 is primarily activated via the phosphoinositide 3-kinase (PI3K)/Akt/mTOR pathway, responding to growth factors, hormones (e.g., insulin), and cellular stressors. Its activation involves phosphorylation at specific residues, enabling interactions with downstream targets such as ion channels, transporters, and transcription factors.
SGK3 is implicated in diverse physiological processes, including electrolyte homeostasis, neuronal excitability, and autophagy. Dysregulation of SGK3 has been linked to pathological conditions such as cancer, neurodegenerative disorders, and metabolic diseases. For instance, SGK3 overexpression is observed in certain cancers (e.g., breast and prostate), where it promotes tumor cell survival under nutrient deprivation or hypoxia.
Recombinant SGK3 protein is engineered for in vitro studies to elucidate its molecular functions and therapeutic potential. Produced using heterologous expression systems (e.g., *E. coli*, mammalian cells), the recombinant protein retains kinase activity and structural integrity, enabling biochemical assays, drug screening, and interaction studies. Researchers utilize it to investigate SGK3’s role in signaling cascades, its crosstalk with other kinases (e.g., Akt), and its modulation by small molecules or genetic inhibitors.
Additionally, SGK3’s unique N-terminal phosphoinositide-binding domain (PHD) distinguishes it from other SGK isoforms, influencing its subcellular localization and activation. Recombinant SGK3 variants, including phosphorylation-mimetic or domain-deleted forms, are valuable tools for dissecting structure-function relationships and developing isoform-specific therapies. Overall, SGK3 recombinant protein serves as a pivotal resource for advancing understanding of cellular signaling and disease mechanisms.
