Invitrogen™ MD-1 Polyclonal Antibody

MD-1, also known as LY86, is a glycoprotein involved in innate immunity. It is a component of the RP105/MD-1 complex, which is expressed primarily in immune cells like B-cells. MD-1 is structurally similar to MD-2, sharing only 16% sequence identity, yet both are implicated in lipopolysaccharide recognition. The protein contains the ML (MD-2-related lipid-recognition) domain, which is conserved across various species and mediates diverse biological functions by interacting with specific lipids. Structurally, MD-1 is characterized by a beta-rich fold consisting of multiple strands, which is integral to its biological activities. Though MD-1 mainly associates with RP105, its role in lipid recognition suggests functional similarities with proteins such as GM2A and NPC2, implying participation in broader immune signaling pathways.
