Characterizing Solution Surface Loop Conformational Flexibility of the GM2 Activator Protein
GM2AP has a β-cup topology with numerous X-ray structures showing multiple conformations for some of the surface loops, revealing conformational flexibility that may be related to function, where function is defined as either membrane binding associated with ligand binding and extraction or interaction with other proteins. Here, site-directed spin labeling (SDSL) electron paramagnetic resonance...
متن کاملA 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 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)...
متن کاملProtein Conformational Flexibility Enables the Formation of Dense Liquid Clusters: Tests Using Solution Shear.
According to recently proposed two-step nucleation mechanisms, crystal nuclei form within preexisting dense liquid clusters. Clusters with radii about 100 nm, which capture from 10(-7) to 10(-3) of the total protein, have been observed with numerous proteins and shown to host crystal nucleation. Theories aiming to understand the mesoscopic size and small protein fraction held in the clusters ha...
متن کاملOxidized Low-density Lipoprotein Upregulates GM2 Activator Protein Gene Expression
Oxidized low-density lipoprotein (LDL) has been shown to be a powerful regulator of gene expression in monocyte-derived macrophage. To determine the effects of oxidized LDL on macrophage gene expression, macrophages incubated with native or oxidized LDL were analyzed by differential display technique. The differentially expressed cDNA (387 bp) fragment by oxidized LDL showed 100% homology to th...
