WebJul 13, 2010 · Calcium/calmodulin-dependent myosin light chain kinase implicated in smooth muscle contraction via phosphorylation of myosin light chains (MLC). Also regulates actin-myosin interaction through a non-kinase activity. Phosphorylates PTK2B/PYK2 and myosin light-chains. WebIsoforms of myosin light chain kinase (MLCK) exist in smooth and skeletal muscle and in other tissues including the brain. They all exist as monomers that can be quite variable in …
WebThe siRNA silencing of TAK-1 and p65/p50 subunit inhibited the LPS-induced increase in intestinal TJ permeability and the increase in myosin light chain kinase (MLCK) expression, confirming the regulatory role of TAK-1 and NF-κB p65/p50 in up-regulating MLCK expression and the subsequent increase in TJ permeability. WebApr 10, 2024 · Intestinal epithelia express two long myosin light chain kinase (MLCK) splice variants, MLCK1 and MLCK2. Unlike MLCK2, MLCK1 is concentrated at the perijunctional actomyosin ring and this localization is enhanced by tumor necrosis factor (TNF) signaling. Here we sought to identify and characterize the domain(s) that direct basal and TNF …
