Descriptions
Myosin light chain kinases (MLCK) are members of the family of Ca2+-calmodulin-dependent protein kinases. The autoinhibitory pseudosubstrate sequence was identified by sequence similarity with the chicken smooth muscle MLCK (P11799-2). The mutational changes of acidic residues in the catalytic core of the kinase domain, which may interact with the basic residues in the pseudosubstrate sequence, increased the catalytic activity of the kinase domain.

5 GO annotations of cellular component
Name | Definition |
---|---|
cleavage furrow | The cleavage furrow is a plasma membrane invagination at the cell division site. The cleavage furrow begins as a shallow groove and eventually deepens to divide the cytoplasm. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
lamellipodium | A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments. |
stress fiber | A contractile actin filament bundle that consists of short actin filaments with alternating polarity, cross-linked by alpha-actinin and possibly other actin bundling proteins, and with myosin present in a periodic distribution along the fiber. |
5 GO annotations of molecular function
Name | Definition |
---|---|
ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
calmodulin binding | Binding to calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states. |
metal ion binding | Binding to a metal ion. |
myosin light chain kinase activity | Catalysis of the reaction: ATP + myosin-light-chain = ADP + myosin-light-chain phosphate. |
protein kinase activity | Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP. |
1 GO annotations of biological process
Name | Definition |
---|---|
tonic smooth muscle contraction | A process in which force is generated within tonic smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the tonic smooth muscle, the muscle contraction occurs without an ordered sarcomeric structure. Tonic smooth muscle contraction occurs as a sustained continuous contraction. |
