The CPI17a (Ab-38) antibody is a monoclonal antibody specifically designed to target the CPI-17 protein (C-kinase-potentiated protein phosphatase 1 inhibitor of 17 kDa), encoded by the *PPP1R14A* gene. CPI-17 is a critical regulatory protein involved in smooth muscle contraction, acting as a potent inhibitor of myosin phosphatase. Its activity is modulated by phosphorylation via protein kinase C (PKC) or Rho-associated kinase (ROCK), which enhances its ability to suppress myosin phosphatase, leading to increased myosin light chain phosphorylation and sustained muscle contraction. This pathway is particularly significant in vascular and bronchial smooth muscle tone regulation, implicating CPI-17 in hypertension, asthma, and other disorders linked to smooth muscle dysfunction.
The Ab-38 antibody is widely utilized in research to investigate CPI-17 expression and function in physiological and pathological contexts. It has been employed in techniques such as Western blotting, immunohistochemistry, and immunofluorescence to study CPI-17 localization and phosphorylation status in tissues. Studies using this antibody have highlighted CPI-17's role in cancer progression, where its overexpression in certain tumors correlates with enhanced cell survival, metastasis, and chemoresistance. Additionally, it serves as a tool to explore CPI-17's involvement in cardiovascular diseases, neuronal signaling, and metabolic regulation. The antibody's specificity and reliability make it valuable for both basic research and translational studies aiming to dissect CPI-17-related mechanisms or develop therapeutic strategies targeting this pathway.
