LY6G6D,also known as LY6-D, is a type I transmembrane protein belonging to the immunoglobin (Ig) superfamily, that is comprised of cell-surface proteins involved in the immune system and cellular recognition. And it is known to interact with GRB2 and GRB7 in a phosphorylation-dependent manner thus playing an important role in their downstream signal transduction pathways. Diseases associated with LY6G6D include Glucosephosphate Dehydrogenase Deficiency and Anemia, Nonspherocytic Hemolytic, Due To G6pd Deficiency.
