The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 26 kDa (predicted molecular weight: 25 kDa).
FunctionCalcium-dependent phospholipase A2 that selectively hydrolyzes glycerophospholipids in the sn-2 position. Not arachidonic acid-specific but has linoleic acid-specific activity. May play a role in inflammation in psoriatic lesions.
Tissue specificityExpressed in stratified squamous epithelia, such as those in skin and cervix, but not in other tissues. Strongly expressed in the upper spinous layer of the psoriatic epidermis, expressed weakly and discontinuously in atopic dermatitis and mycosis fungoides, and not detected in the epidermis of normal skin.
DomainThe N-terminal C2 domain associates with lipid membranes upon calcium binding. It modulates enzyme activity by presenting the active site to its substrate in response to elevations of cytosolic Ca(2+).
Cellular localizationCytoplasm > cytosol. Cytoplasmic vesicle membrane. Translocates to membrane vesicles in a calcium-dependent fashion. Translocates to perinuclear regions upon ionomycin stimulation.
