Summaries for ABCB5 Gene

Entrez Gene Summary for ABCB5 Gene

  • ABCB5 belongs to the ATP-binding cassette (ABC) transporter superfamily of integral membrane proteins. These proteins participate in ATP-dependent transmembrane transport of structurally diverse molecules ranging from small ions, sugars, and peptides to more complex organic molecules (Chen et al., 2005 [PubMed 15760339]).[supplied by OMIM, Mar 2008]

GeneCards Summary for ABCB5 Gene

ABCB5 (ATP Binding Cassette Subfamily B Member 5) is a Protein Coding gene. Diseases associated with ABCB5 include placental site trophoblastic tumor. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and ABC-family proteins mediated transport. GO annotations related to this gene include ATPase activity and efflux transmembrane transporter activity. An important paralog of this gene is ABCB11.

UniProtKB/Swiss-Prot for ABCB5 Gene

  • Drug efflux transporter present in a number of stem cells that acts as a regulator of cellular differentiation. Able to mediate efflux from cells of the rhodamine dye and of the therapeutic drug doxorubicin. Specifically present in limbal stem cells, where it plays a key role in corneal development and repair.

Tocris Summary for ABCB5 Gene

  • ATP-binding cassette (ABC) transporters form one of the largest groups of paralogous protein families that have a wide diversity of functions and substrates. Specificity has been shown for small and large molecules, highly charged molecules and highly hydrophobic systems.

    • Acts as a marker of stem-like cells (CSC) in a number of malignancies (PubMed:24934811). Associated with clinical drug resistance, tumor progression and disease recurrence in malignant melanoma and acute leukemias. Responsible for the resistance to doxorubicin of a subset of malignant melanomas. ABCB5-expressing cells selectively survive when exposed to dacarbazine drug, the reference treatment of metastatic melanoma, vemurafenib and other various chemotherapeutic drugs, suggesting that anti-melanoma chemotherapy participates to the chemoresistance acquisition by selecting tumor cell subpopulations expressing ABCB5 (PubMed:22784549, PubMed:22044138, PubMed:22675422, PubMed:23770371, PubMed:24934811). Present in melanoma-initiating cells that acts as an enhancer of tumor growth by promoting CSC maintenance and tumor growth by controlling IL-1beta (IL1B) secretion to maintain slow-cycling, chemoresistant cells through an IL-1beta (IL1B)/IL8/CXCR1 cytokine signaling circuit (PubMed:24934811).

mRNA Expression by UniProt/SwissProt for ABCB5 Gene

Tissue specificity: Expressed by CD133-expressing progenitor cells among epidermal melanocytes (at protein level). Widely expressed with specific expression in pigment cells. Highly expressed in several malignant tissues: highly expressed in clinical melanomas, with low expression in normal skin. In melanoma, marks malignant melanoma-initiating cells (MMIC), in which clinical virulence resides as a consequence of unlimited self-renewal capacity, resulting in inexorable tumor progression and metastasis. Also highly expressed in a number of leukemia cells. Expressed in basal limbal epithelium.
