Description:
Chronic granulomatous diseases (CGDs) are characterized by recurrent infections resulting from impaired superoxide production by a phagocytic cell, nicotinamide adenine dinucleotide phosphate (reduced) (NADPH) oxidase. Complementary DNAs were cloned that encode the 67-kilodalton (kD) cytosolic oxidase factor (p67), which is deficient in 5% of CGD patients. Recombinant p67 (r-p67) partially restored NADPH oxidase activity to p67-deficient neutrophil cytosol from these patients. The p67 cDNA encodes a 526-amino acid protein with acidic middle and carboxyl-terminal domains that are similar to a sequence motif found in the noncatalytic domain of src-related tyrosine kinases. This motif was recently noted in phospholipase C-gamma, nonerythroid alpha-spectrin (fodrin), p21ras-guanosine triphophatase-activating protein (GAP), myosin-1 isoforms, yeast proteins cdc-25 and fus-1, and the 47-kD phagocyte oxidase factor (p47), which suggests the possibility of common regulatory features.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leto, T L -- Lomax, K J -- Volpp, B D -- Nunoi, H -- Sechler, J M -- Nauseef, W M -- Clark, R A -- Gallin, J I -- Malech, H L -- I01 BX000513/BX/BLRD VA/ -- New York, N.Y. -- Science. 1990 May 11;248(4956):727-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Clinical Investigation, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1692159" target="_blank"〉PubMed〈/a〉
