Cyba - cytochrome b-245, alpha polypeptide

Predicted to enable SH3 domain binding activity; electron transfer activity; and protein heterodimerization activity. Predicted to contribute to superoxide-generating NAD(P)H oxidase activity. Involved in innate immune response. Acts upstream of or within positive regulation of mucus secretion; reactive oxygen species metabolic process; and regulation of release of sequestered calcium ion into cytosol. Located in endosome. Part of NADPH oxidase complex. Is expressed in several structures, including genitourinary system; hemolymphoid system; inner ear; limb; and liver. Human ortholog(s) of this gene implicated in artery disease (multiple); asthma; chronic obstructive pulmonary disease; and phagocyte bactericidal dysfunction (multiple). Orthologous to human CYBA (cytochrome b-245 alpha chain). [provided by Alliance of Genome Resources, Apr 2022]
