Recombinant Human Acid ceramidase (ASAH1) is a partial length protein expressed with N-terminal 6xHis-SUMO-tagged in the E.coli. Its expression region corresponds to 22-395aa of human ASAH1 protein. Its purity was determined by SDS-PAGE and reached up to 90% and presented a molecular mass band of 58.7 kDa on the gel. This recombinant ASAH1 protein may be used to synthesize antibodies against ASAH1. ASAH1 proteins in-stock are available.
ASAH1 is lysosomal ceramidase that hydrolyzes sphingolipid ceramides into sphingosine and free fatty acids at acidic pH. Ceramides, sphingosine, and its phosphorylated form sphingosine-1-phosphate are bioactive lipids that mediate cellular signaling pathways regulating several biological processes including cell proliferation, apoptosis and differentiation. This enzyme is overexpressed in multiple human cancers and may play a role in cancer progression. ASAH1 mutations are associated with the lysosomal storage disorder, Farber lipogranulomatosis, and a neuromuscular disorder, spinal muscular atrophy with progressive myoclonic epilepsy.

Target Background

Lysosomal ceramidase that hydrolyzes sphingolipid ceramides into sphingosine and free fatty acids at acidic pH. Ceramides, sphingosine, and its phosphorylated form sphingosine-1-phosphate are bioactive lipids that mediate cellular signaling pathways regulating several biological processes including cell proliferation, apoptosis and differentiation. Has a higher catalytic efficiency towards C12-ceramides versus other ceramides. Also catalyzes the reverse reaction allowing the synthesis of ceramides from fatty acids and sphingosine. For the reverse synthetic reaction, the natural sphingosine D-erythro isomer is more efficiently utilized as a substrate compared to D-erythro-dihydrosphingosine and D-erythro-phytosphingosine, while the fatty acids with chain lengths of 12 or 14 carbons are the most efficiently used. Has also an N-acylethanolamine hydrolase activity. By regulating the levels of ceramides, sphingosine and sphingosine-1-phosphate in the epidermis, mediates the calcium-induced differentiation of epidermal keratinocytes. Also indirectly regulates tumor necrosis factor/TNF-induced apoptosis. By regulating the intracellular balance between ceramides and sphingosine, in adrenocortical cells, probably also acts as a regulator of steroidogenesis.; May directly regulate steroidogenesis by binding the nuclear receptor NR5A1 and negatively regulating its transcriptional activity.
