Target Background

(From Uniprot)
Energy-dependent efflux transporter responsible for decreased drug accumulation in multidrug-resistant cells. Specifically present in limbal stem cells, where it plays a key role in corneal development and repair.
Gene References into Functions
  1. Interaction analysis demonstrated that the following genotypes: MS4A14 DI+II, SLC2A DI+II and ABCB 5 CG+GG, were associated with a prothrombin time >/=12 sec and with Recurrent pregnancy loss (RPL) risk PMID: 29956771
  2. No significant influence of the three newly identified ABCB5 polymorphisms. PMID: 26975227
  3. The ABCB5 activates the NF-kappaB pathway by inhibiting p65 ubiquitination to enhance p65 protein stability. PMID: 28821433

  10. ATP-binding cassette member B5 (ABCB5) identifies dermal immunoregulatory cells capable of exerting therapeutic immunoregulatory functions through engagement of programmed cell death 1. PMID: 26321644
  11. This is the first study showing the relationship between miR-340-5p and expression of ABCB5 in melanoma cells PMID: 26554847
  12. c-MYC confers resistance to 5-fluorouracil through regulating ABCB5 expression in human colon cancer cells. PMID: 25689483
  13. ABCB5 alleles alter susceptibility to haloperidol-induced toxicity (HIT) in mouse and humans. PMID: 25647612
  14. The resistance of CD133(+) melanoma subpopulation is attributed to the enhanced drug efflux mediated by ATP-binding cassette sub-family B member 5 (ABCB5), since the knockdown of ABCB5 was found to sensitize CD133(+) cells to CAPE. PMID: 25449786
  15. In melanoma-initiating cells, ABCB5 controls IL1beta secretion, which serves to maintain slow cycling, chemoresistant cells through an IL1beta/IL8/CXCR1 cytokine signaling circuit. PMID: 24934811
  16. Suggest that the helicase HAGE has a key role in the resistance of ABCB5+ malignant melanoma stem cells to IFNalpha treatment by promoting SOCS1 expression. PMID: 24525737
  17. ABCB5 and MDR1 gene expression correlate with drug resistance in acute leukemia patients. PMID: 24804815
  18. ATP-binding cassette, sub-family B, member 5 (ABCB5) marks limbal stem cells (LSCs) and is required for LSC maintenance, corneal development and repair PMID: 25030174
