产品介绍：MaxiK channels are large conductance, voltage ａnd calcium-sensitive potassium channels which are fundamental to the control of smooth muscle tone ａnd neuronal excitability. MaxiK channels can be formed by 2 subunits: the pore-forming alpha subunit, which is the product of this gene, ａnd the modulatory beta subunit. Intracellular calcium regulates the physical association between the alpha ａnd beta subunits. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008].Function : Potassium channel activated by both membrane depolarization or increase in cytosolic Ca（2+） that mediates export of K（+）. It is also activated by the concentration of cytosolic Mg（2+）. Its activation dampens the excitatory events that elevate the cytosolic Ca（2+） concentration and/or depolarize the cell membrane. It therefore contributes to repolarization of the membrane potential. Plays a key role in controlling excitability in a number of systems, such as regulation of the contraction of smooth muscle, the tuning of hair cells in the cochlea, regulation of transmitter release, ａnd innate immunity. In smooth muscles, its activation by high level of Ca（2+）, caused by ryanodine receptors in the sarcoplasmic reticulum, regulates the membrane potential. In cochlea cells, its number ａnd kinetic properties partly determine the characteristic frequency of each hair cell ａnd thereby helps to establish a tonotopic map. Kinetics of KCNMA1 channels are determined by alternative splicing, phosphorylation status ａnd its combination with modulating beta subunits. Highly sensitive to both iberiotoxin （IbTx） ａnd charybdotoxin （CTX）.Subunit : Belongs to the potassium channel family. Calcium-activated （TC 1.A.1.3） subfamily. KCa1.1/KCNMA1 sub-subfamily.Contains 1 RCK N-terminal domain.Subcellular Location : Membrane.Tissue Specificity : Widely expressed. Except in myocytes, it is almost ubiquitously expressed.Post-translational modifications : Phosphorylated （Probable）. Phosphorylation by kinases such as PKA and/or PKG. In smooth muscles, phosphorylation affects its activity.DISEASE : Defects in KCNMA1 are the cause of generalized epilepsy ａnd paroxysmal dyskinesia （GEPD） [MIM:609446]. Epilepsy is one of the most common ａnd debilitating neurological disorders. Paroxysmal dyskinesias are neurological disorders characterized by sudden, unpredictable, disabling attacks of involuntary movement often requiring life-long treatment. The coexistence of epilepsy ａnd paroxysmal dyskinesia in the same individual or family is an increasingly recognized phenomenon. Patients manifest absence seizures, generalized tonic-clonic seizures, paroxysmal nonkinesigenic dyskinesia, involuntary dystonic or choreiform movements. Onset is usually in childhood ａnd patients may have seizures only, dyskinesia only, or both.Similarity : Belongs to the potassium channel family. Calcium-activated （TC 1.A.1.3） subfamily. KCa1.1/KCNMA1 sub-subfamily.Contains 1 RCK N-terminal domain.
