ATP Binding Cassette subfamily G, Member 5, Control Peptide (ABCG5, Sterolin-1)
Molecular Biology Storage: -20CShipping: Blue Ice
Control peptide for A0004-05C, polyclonal antibody to ABCG5.

The ATP binding cassette (ABC) superfamily of membrane transporters is one of the largest protein classes known, and counts for numerous proteins involved in trafficking of biological molecules across membranes, host-defense mechanism to xenobiotics. The first known members were Pglycoprotein (P-gp) and multidrug resistant protein (MRP), cause multidrug resistance when transfected into drugsensitive cells. In addition, increasing numbers of ABC proteins have recently been identified. The human ABCG1 (ABC, subfamily G, member 1) gene encodes a member of ABC superfamily that mediates the ATP-dependent translocation of variety of amphiphilic and lipophilic molecules. ABCG proteins were able to transport substances across cellular membranes and against concentration gradient they require an input of energy, which requires the hydrolysis of ATP, directly or indirectly.

ABCG5 gene product a 651aa residue in human, and 652aa each in rat and mouse, plays an important role in the selective transport of cholesterol in and out of the enterocytes and in the selective sterol excretion by liver into bile. Strongly expressed in liver, intestine and colon. Defects in ABCG5 results increased intestinal absorption of sterols and decreased biliary excretion of dietary sterols into bile; the condition is referred as sitosterolemia.
