NCIt synonyms : EST422562; ABCB5beta; ATP-Binding Cassette, Sub-Family B (MDR/TAP), Member 5 wt Allele; ABCB5alpha;
NCIt definition : Human ABCB5 wild-type allele is located in the vicinity of 7p15.3 and is approximately
108 kb in length. This allele, which encodes ATP-binding cassette sub-family B member
5 protein, is involved in the mediation of the transport of small molecules across
membranes. Expression of the gene is linked to drug resistance for a subset of melanomas.;
NCIt note : The ABCB5 gene is expressed as two isoforms with products designated alpha and beta.
The alpha form is a shorter construct produced by alternative splicing. (SwissProt); Depletion of the expression of the ABCB5 gene through RNA interference increases the
drug sensitivity of chemotherapy resistant melanoma cells. (SwissProt);
