Three regions (CDR1; CDR2 and CDR3) of amino acid sequence in the IMMUNOGLOBULIN VARIABLE REGION that are highly divergent. Together the CDRs from the light and heavy immunoglobulin chains form a surface that is complementary to the antigen. These regions are also present in other members of the immunoglobulin superfamily, for example, T-cell receptors (RECEPTORS, ANTIGEN, T-CELL).

ATP Binding Cassette, Sub Family B Proteins
- A subfamily transmembrane the superfamily TRANSPORTERS that closely related in GLYCOPROTEIN. When overexpressed, function as dependent efflux pumps able extrude lipophilic drugs, especially ANTINEOPLASTIC AGENTS, from cells causing resistance (DRUG RESISTANCE, MULTIPLE). Although P-Glycoproteins share functional similarities to MULTIDRUG RESISTANCE-ASSOCIATED PROTEINS they are two distinct subclasses of ATP-BINDING CASSETTE TRANSPORTERS, and have little sequence homology.
