SpecificityReacts with a conserved cytoplasmic epitope of the plasma membrane-associated 170 kDa P-gp, member of the superfamily of transmembrane transporters. JSB-1 detects P-gp overexpression in human tumor cells of all different histogenetic derivations.

JSB-1 does not cross-react with MDR3 P-glycoprotein. JSB-1 has been shown to cross-react with Pyruvate Carboxylase (PC), an abundant Mr 130,000 mitochondrial enzyme, on both immunoblots and immunohistochemical tissue sections [Rao et al. (1995). J Histo. Cytochem. 43(12):1187-1192.] Unequivocal plasma membrane patterns of immunostaining represent true P-glycoprotein ex-presssion. Weak homogeneous, cytoplasmic, or granular patterns of reactivity may represent staining of the PC cross-reactive epitope rather than positive staining for P-glycoprotein.

Entrez Gene Number
Entrez Gene SummaryThe membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. The protein encoded by this gene is an ATP-dependent drug efflux pump for xenobiotic compounds with broad substrate specificity. It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs. This protein also functions as a transporter in the blood-brain barrier.
