STK17B, also known as serine/threonine kinase 17B, is a member of the death-associated protein kinase (DAPK) family. It plays a regulatory role in apoptosis, autophagy, and cellular stress responses. The protein is encoded by the STK17B gene, located on human chromosome 2q14.3. and is characterized by a conserved kinase domain that mediates phosphorylation-dependent signaling. STK17B is implicated in DNA damage repair pathways, with studies suggesting its involvement in p53-mediated apoptosis and modulation of reactive oxygen species (ROS) homeostasis. Its expression is tissue-specific, with higher levels observed in organs like the liver, kidney, and brain.
Recombinant STK17B protein is engineered for in vitro studies to elucidate its biochemical properties, substrate interactions, and regulatory mechanisms. Produced typically in bacterial or mammalian expression systems, the purified protein retains kinase activity, enabling researchers to analyze phosphorylation events, screen kinase inhibitors, or study structural features via crystallography. Dysregulation of STK17B has been linked to diseases such as cancer, neurodegenerative disorders, and metabolic syndromes, making its recombinant form valuable for drug discovery and mechanistic studies. Recent research highlights its dual role as both a pro-apoptotic factor and a potential oncogene, depending on cellular context, underscoring the need for further exploration of its pathophysiological relevance.
