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.

7 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
dendrite A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
dendritic spine A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.
neuronal cell body The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
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.
synaptic vesicle A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.
terminal bouton Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal bouton is a specialized region of it.

4 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.
myosin light chain binding Binding to a light chain of a myosin complex.
myosin light chain kinase activity Catalysis of the reaction

14 GO annotations of biological process

Name Definition
cardiac muscle cell differentiation The process in which a cardiac muscle precursor cell acquires specialized features of a cardiac muscle cell. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction.
cardiac muscle tissue morphogenesis The process in which the anatomical structures of cardiac muscle tissue are generated and organized.
neuromuscular synaptic transmission The process of synaptic transmission from a neuron to a muscle, across a synapse.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
positive regulation of fast-twitch skeletal muscle fiber contraction Any process that activates or increases the frequency, rate or extent of fast-twitch skeletal muscle contraction.
positive regulation of gene expression Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
regulation of MAPK cascade Any process that modulates the frequency, rate or extent of signal transduction mediated by the MAP kinase (MAPK) cascade.
regulation of muscle filament sliding Any process that modulates the frequency, rate or extent of muscle filament sliding.
regulation of neuronal synaptic plasticity A process that modulates neuronal synaptic plasticity, the ability of neuronal synapses to change as circumstances require. They may alter function, such as increasing or decreasing their sensitivity, or they may increase or decrease in actual numbers.
skeletal muscle cell differentiation The process in which a relatively unspecialized cell acquires specialized features of a skeletal muscle cell, a somatic cell located in skeletal muscle.
skeletal muscle satellite cell differentiation The process in which a relatively unspecialized cell acquires specialized features of a satellite cell.
striated muscle contraction A process in which force is generated within striated muscle tissue, resulting in the shortening of the muscle. 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. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope.
synaptic vesicle transport The directed movement of synaptic vesicles.
water transport The directed movement of water (H2O) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
