Mycobacterial protein HbhA binds human complement component C3.
Mycobacterium tuberculosis and Mycobacterium avium are facultative intracellular pathogens that are able to survive and replicate in mononuclear phagocytes. Human complement component C3 has previously been shown to mediate attachment and phagocytosis of these bacteria by mononuclear phagocytes. In this study, a C3 ligand affinity blot protocol was used to identify a 30-kDa C3-binding protein i...
متن کاملEcoRI polymorphism in the human third complement component (C3) gene.
Source/Description A cDNA fragment, pC3.11 (1) was used as probe. Polymorphisms: EcoRI cleavage of genomic DNA reveals a 2 allele polymorphism with band sizes of 5.2 and 5.6 kb. Invariant bands of 11.5, 11.0, 9.0 and 3 0 kb were also present. Frequency: Estimated from 35 unrelated Caucasians. Allele Frequency Dl 5.2 0.67 D2 5.6 0.33 Chromosomal Localisation: The human C3 gene had been assigned ...
متن کاملMolecular basis of polymorphisms of human complement component C3
C3 exhibits two common allotypic variants that may be separated by gel electrophoresis and are called C3 fast (C3 F) and C3 slow (C3 S). C3 F, the less common variant, occurs at appreciable frequencies only in Caucasoid populations (gene frequency = 0.20). An increased prevalence of the C3 F allele has been reported in patients with partial lipodystrophy, IgA nephropathy, and Indian childhood h...
متن کاملMonoglucosylated glycans in the secreted human complement component C3: implications for protein biosynthesis and structure.
The monoglucosylated oligomannose N-linked oligosaccharide (Glc(1)Man(9)GlcNAc(2)) is a retention signal for the calnexin-calreticulin quality control pathway in the endoplasmic reticulum. We report here the presence of such monoglucosylated N-glycans on the human complement serum glycoprotein C3. This finding represents the first report of monoglucosylated glycans on a human serum glycoprotein...
متن کاملComplement component C3 binds to activated normal platelets without preceding proteolytic activation and promotes binding to complement receptor 1.
It has been reported that complement is activated on the surface of activated platelets, despite the presence of multiple regulators of complement activation. To reinvestigate the mechanisms by which activated platelets bind to complement components, the presence of complement proteins on the surfaces of nonactivated and thrombin receptor-activating peptide-activated platelets was analyzed by f...
