A protein activator for the enzymic hydrolysis of GM2 ganglioside.
A protein activator (GMz-activator) specific for stimulating the hydrolysis of G M ~ ganglioside (GalNAcb1 4GalC3 + 2aNeuAc]/?l-+ 4Glcb1-+ 1’Cer) by &hexosaminidase A has been purified over 1OS-fold with a high yield from human liver. The purification procedure includes the adjustment of the pH of liver extract to pH 4.3, followed by ammonium sulfate precipitation, Sephadex G-200 filtration, an...
متن کاملGanglioside GM2-activator protein and vesicular transport in collecting duct intercalated cells.
This study describes the molecular characterization of an antigen defined by an autoantibody from a woman with habitual abortion as GM2-activator protein. The patient showed no disorder of renal function. Accidentally with routine serum screening for autoantibodies, an immunoreactivity was found in kidney collecting duct intercalated cells. Three distinct patterns of immunostaining of intercala...

The hydrolysis in lysosomes of GM2 ganglioside to GM3 ganglioside requires the correct synthesis, intracellular assembly and transport of three separate gene products; i.e., the alpha and beta subunits of heterodimeric beta-hexosaminidase A, E.C. # 3.2.1.52 (encoded by the HEXA and HEXB genes, respectively), and the GM2-activator protein (GM2AP, encoded by the GM2A gene). Mutations in any one o...
متن کاملRabbit Anti-Ganglioside GM2 Polyclonal Antibody
BACKGROUND Introduction: GM2 is a type of ganglioside. It is associated with GM2 gangliosidoses such as Tay-Sachs disease.
متن کاملTwo polymorphisms for the human GM2 activator protein gene.
Source/Description: A 300 bp HincII/EcoRI fragment of the human G^ activation protein cDNA (1) was subcloned into Bluescript vector and used as a probe. Polymorphism: Mspl identifies a two allele polymorphism with bands at either 3.4 kb (Al) or 2.9 kb (A2) and invariant bands at 1.0 kb, 1.8 kb and 4.0 kb. Rsal identifies a two allele polymorphism with a band at either 4.1 kb (Bl) or 3.4 kb (B2)...
