alternative products:Isoform 1 and isoform 2 are expressed in the same tissues,catalytic activity:ATP + H(2)O + Ca(2+)(Cis) = ADP + phosphate + Ca(2+)(Trans).,disease:Defects in ATP2C1 are the cause of Hailey-Hailey disease (HHD) [MIM:169600]; also known as benign familial pemphigus. HHD is an autosomal dominant disorder characterized by persistent blisters and suprabasal cell separation (acantholysis) of the epidermis, due to impaired keratinocyte adhesion. Patients lacking all isoforms except isoform 2 have HHD.,function:This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of the calcium.,similarity:Belongs to the cation transport ATPase (P-type) family.,similarity:Belongs to the cation transport ATPase (P-type) family. Type IIA subfamily.,tissue specificity:Found in most tissues except colon, thymus, spleen and leukocytes. Most abundant in keratinocytes and kidney.,
Golgi apparatus, trans-Golgi network membrane ; Multi-pass membrane protein . Golgi apparatus, Golgi stack membrane ; Multi-pass membrane protein . During neuron differentiation, shifts from juxtanuclear Golgi position to multiple Golgi structures distributed over the neural soma with a predominance in the apical dendritic trunk. .
Found in most tissues except colon, thymus, spleen and leukocytes (PubMed:15831496). Expressed in keratinocytes (at protein level) (PubMed:15831496, PubMed:14632183).
