Phosphoinositol 3-phosphate regulates reactive oxygen species production by maintaining p40phox and p67phox at the phagosomal membrane.
-
NCF4 polymorphism was associated with Crohn's disease, but not ulcerative colitis in Caucasian--{REVIEW}
-
NCF4 may induce ex- pression of NADPH oxidase enzymes, such as p67phox, p47phox, p22phox and NOX2, which lead to increased ROS levels.
-
Germline variation in NCF4, an innate immunity gene, is associated with an increased risk of colorectal cancer.
-
The contribution of the functionally relevant NADPH polymorphisms rs1883112 and rs4673 to anthracycline-related heart lesions provides a plausible explanation for their modulation of cardiotoxicity.
-
Constitutive and inducible intracellular production of reactive oxygen species (ROS) is higher in B cells expressing functional p40phox, supporting a direct role for p40phox in regulating B cell intracellular ROS generation.
-
Genome-wide association studies-reported associations between the NELL1, NCF4, and FAM92B genes and susceptibility to Crohn's disease could not be replicated in Canadian children and young adults.
-
Younger age at diagnosis, complicated disease behavior, and ileal disease location are risk factors for perianal CD. First report of an association of the NCF4 gene with perianal disease.
-
cooperation of p40(phox) with p47(phox) for Nox2-based NADPH oxidase activation during Fcgamma receptor (FcgammaR)-mediated phagocytosis
-
Results demonstrate that PBEF can prime for PMN respiratory burst activity by promoting p40 and p47 translocation to the membrane.
-
no association between SNP rs4821544 and the presence of granulomas in Crohn's disease
-
cytosolic localisation depends on direct interaction with F-actin
-
All mutations and some polymorphisms identified in the NCF4 gene in the autosomal forms of chronic granulomatous disease are listed. Review.
-
p40(phox) functions primarily to regulate Fc gamma receptor-induced NADPH oxidase activity rather than assembly, and stimulates superoxide production via a phosphatidylinositol-3-phosphate signal that increases after phagosome internalization.
-
detailed study of the protein-protein interactions that occur in the p40-p47-p67(phox) complex of the resting oxidase
-
p22(phox), gp91(phox), p47(phox), p67(phox), and p40(phox) existed as a functional complex in the cytoskeletal fraction.
-
Involvement of protein kinase D in Fc gamma-receptor activation of the NADPH oxidase in neutrophils
-
Multiple PU.1 sites cooperate in the regulation of p40(phox) transcription during granulocytic differentiation of myeloid cells.
-
p40phox and p47phox PX domains interact with PI-containing membranes
-
A model is proposed in which phosphorylation of p40PHOX on threonine 154 leads to an inhibitory conformation that shifts the balance toward an inhibitory role and blocks NADPH oxidase activation.
