malfunction
metabolism
first of three steps to remove 2 C4 methyl groups from an intermediate in ergosterol biosynthesis in the sterol biosynthetic pathway, an enzymatic complex is formed with other enzymes in the pathway
physiological function
-
the enzyme regulates epidermal growth factor receptor signaling and vesicular trafficking
-
deficiency of sterol C4 methyl oxidase, is associated with microcephaly, congenital cataracts, and growth delay in infancy
malfunction
mutations in methyl sterol oxidase cause psoriasiform dermatitis, arthralgias, congenital cataracts, microcephaly, and developmental delay. Enzyme deficiency also substantially alters immunocyte phenotype and in vitro function
