Energy-dependent efflux transporter responsible for decreased drug accumulation in multidrug-resistant cells (PubMed:12960149, PubMed:22306008, PubMed:15899824, PubMed:15205344).

Specifically present in limbal stem cells, where it plays a key role in corneal development and repair (By similarity).

Miscellaneous

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 in 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).5 Publications

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.8 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iA4521B83E0D234CF
