Description : The CYBA gene encodes the alpha subunit, also known as the light chain, of cytochrome
b(-245), which is a component of the NADPH oxidase (NOX) complex responsible for the
respiratory burst in phagocytes. The CYBB gene (300481) is an X-linked gene which
encodes the cytochrome b beta subunit, also known as the heavy chain. Dinauer et al.
(1990) and Schapiro et al. (1991) referred to the 22-kD gene product as p22-phox (for
phagocyte oxidase). De Boer et al. (1992) referred to the product of the CYBA gene
as the alpha subunit of cytochrome b(558) or p22-phox. They mentioned an international
agreement on designations.;
