Hexosaminidase A/HEXA Antibody (714729)

This product is produced by and ships from R&D Systems, Inc., a Bio-Techne brand.

beta -hexosaminidases are enzymes involved in the hydrolysis of terminal N-acetyl-D-hexosamine residues in GM2 gangliosides and globo-sphingolipids in lysosomes (1‑4). The enzymes are composed of two alpha and/or beta subunits, which are coded by HEXA and HEXB genes, respectively. Different association of the alpha and beta subunits gives rise to beta ‑hexosaminidase isoforms A, B and S (Hex A, B and S) (5), which have the composition of alpha beta , beta beta and alpha alpha , respectively. Our recombinant HEXA is presumably isoform Hex S, because only alpha subunit was expressed. Hex S is suggested to releases non‑reducing end N-acetylgalactosamine residues from dermatan sulfate, chondroitin sulfate and sulfated glycolipid SM2 (6). Recombinant HEXA is also highly active on 4-methylumbelliferyl-N-acetyl-beta -D-glucosaminide (6). Mutations in HEXA and HEXB genes cause lysosomal lipid storage disorders. Specifically, mutations of HEXA cause Tay-Sachs disease, manifested by the harmful accumulation of ganglioside GM2 in tissues and nerve cells in the brain (7‑10). Children with this disease usually die by age 4.
