Descriptions
Myosin light chain kinases (MLCK) are members of the family of Ca2+-calmodulin-dependent protein kinases. This enzyme contains an autoinhibitory pseudosubstrate sequence that blocks the substrate-binding site of the kinase. The autoinhibitory sequence makes an extensive network of contacts on the surface of the larger C-domain of the catalytic core extending towards the catalytic cleft with the CaM-binding sequence to block the regulatory light chain of sarcomeric myosin, but not ATP binding in the catalytic core N-domain.

4 GO annotations of cellular component
| Name | Definition |
|---|---|
| actin cytoskeleton | The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes. |
| 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. |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
3 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| calmodulin-dependent protein kinase activity | Calmodulin-dependent catalysis of the reactions |
| myosin light chain kinase activity | Catalysis of the reaction |
9 GO annotations of biological process
| Name | Definition |
|---|---|
| cardiac myofibril assembly | The process whose specific outcome is the progression of the cardiac myofibril over time, from its formation to the mature structure. A cardiac myofibril is a myofibril specific to cardiac muscle cells. |
| cellular response to interleukin-1 | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an interleukin-1 stimulus. |
| intracellular signal transduction | The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. |
| positive regulation of apoptotic process | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| positive regulation of sarcomere organization | Any process that increases the rate, frequency or extent of myofibril assembly by organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs. |
| protein phosphorylation | The process of introducing a phosphate group on to a protein. |
| regulation of vascular permeability involved in acute inflammatory response | Any process that modulates the extent to which blood vessels can be pervaded by fluid contributing to an acute inflammatory response. |
| sarcomere organization | The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs. |
| sarcomerogenesis | The process in which sarcomeres are added in series within a fiber. |
