Immunochemical characterization of myosin-specific phosphatase 1 regulatory subunits in bovine endothelium.


We have previously shown that myosin-specific phosphatase 1 (PPase 1) activity is critical for maintaining endothelial cell barrier function (Verin et al. [1995] Am. J. Physiol. 269:L99-L108). To further characterize myosin-specific PPase 1 in endothelium, we generated antibodies specific to published sequences of the myosin-associated PPase 1 regulatory… (More)
