靶點詳情

  • 功能：
    Hydrolyzes the non-reducing end N-acetyl-D-hexosamine and/or sulfated N-acetyl-D-hexosamine of glycoconjugates, such as the oligosaccharide moieties from proteins and neutral glycolipids, or from certain mucopolysaccharides. The isozyme B does not hydrolyze each of these substrates, however hydrolyzes efficiently neutral oligosaccharide. Only the isozyme A is responsible for the degradation of GM2 gangliosides in the presence of GM2A. During fertilization is responsible, at least in part, for the zona block to polyspermy. Present in the cortical granules of non-activated oocytes, is exocytosed during the cortical reaction in response to oocyte activation and inactivates the sperm galactosyltransferase-binding site, accounting for the block in sperm binding to the zona pellucida.
  • 基因功能參考文獻：
    1. mast cell granule beta-hexosaminidase is crucial for defense against bacterial invasion, but is not involved in the allergic response. the bactericidal mechanism of beta-hexosaminidase involves degradation of bacterial cell wall peptidoglycan. PMID: 25015817
    2. transgenic inducible strains of Sandhoff disease mice provide a dynamic platform with which to explore the pathophysiological sequelae immediately after loss of neuronal lysosomal beta-hexosaminidase activity. PMID: 23028353
    3. Thymic involution and corticosterone level in Sandhoff disease model mice. PMID: 21598013
    4. These data suggest that the restricted ketogenic diet and N-butyldeoxynojirimycin may be a potential combinatorial therapy for Sandhoff disease. PMID: 20374428
    5. Data suggest that pathogenesis of Sandhoff disease (heritable beta-hexosaminidase deficiency) involves an increase in macrophage-inflammatory protein 1alpha that induces monocytes to infiltrate the CNS and trigger neuronal apoptosis. PMID: 15155903
    6. The bicistronic beta-hexosaminidase vector can reverse the biochemical defects and down-stream consequences in Sandhoff neurons, reinforcing its potential for Sandhoff disease in vivo gene therapy. PMID: 16441513
    7. Beta-hexosaminidase is a peptidoglycan hydrolase that surprisingly exerts its mycobactericidal effect at the macrophage plasma membrane during mycobacteria-induced secretion of lysosomes PMID: 18180457
    8. There was no change in the level of GM2 storage and pro-apoptotic activity or astrocyte activation in HexB-/- knockout mice PMID: 18657867
