Genes affected
MREG (HGNC:25478): (melanoregulin) Predicted to enable phosphatidylinositol binding activity. Predicted to be involved in melanocyte differentiation; melanosome transport; and phagosome maturation. Predicted to act upstream of or within developmental pigmentation. Predicted to be located in late endosome membrane and melanosome membrane. Predicted to be intrinsic component of organelle membrane. Predicted to be part of protein-containing complex. Predicted to be active in melanosome.
