ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes physiological compounds, and xenobiotics from cells. Participates in physiological processes involving bile acids, conjugated steroids and cyclic nucleotides (PubMed:12764137, PubMed:15537867). Stimulates the ATP-dependent uptake of a range of physiological lipophilic anions, including the glutathione S-conjugates leukotriene C4 and dinitrophenyl S-glutathione, steroid sulfates such as dehydroepiandrosterone 3-sulfate (DHEAS) and estrone 3-sulfate, glucuronides such as estradiol 17-beta-D-glucuronide (E(2)17betaG), the monoanionic bile acids glycocholate and taurocholate, and methotrexate (PubMed:15537867, PubMed:25896536). Enhances also the cellular extrusion of cAMP and cGMP (PubMed:12764137, PubMed:15537867). Confers resistance to anticancer drugs, such as 5-fluorouracil (5-FU) and methotrexate (PubMed:25896536, PubMed:15537867, PubMed:12764137). Probably functions to secrete earwax (PubMed:16444273, PubMed:19383836). Required for the secretion of components contributing to axillary odor formation (PubMed:19710689, PubMed:12764137, PubMed:15537867, PubMed:16444273, PubMed:19383836, PubMed:25896536).

Expressed in many tissues. Not expressed in kidney, spleen and colon. Highly expressed in breast cancer. Expressed at moderate levels in normal breast and testis and at very low levels in liver, brain and placenta (PubMed:11483364, PubMed:11591886, PubMed:19383836, PubMed:19710689). Localizes to axons of the CNS and peripheral nervous system (at protein level) (PubMed:16359813). Polymorphism in ABCC11 is associated with variation in apocrine gland secretion [MIM:117800]. This determines different ear wax phenotypes, presence or absence of axillary odor, and variation in colostrum secretion. Characteristic of earwax and strength of axillary odor are most likely interconnected. Human earwax is a Mendelian trait consisting of wet and dry types. The wet earwax is brownish and sticky, whereas the dry type lacks cerumen. The wet cerumen phenotype is completely dominant. The dry type is seen frequently (80-95%) among East Asians, but uncommon (0-3%) in populations of European and African origins. Intermediate frequencies (30-50%) of the dry type are seen in populations of Southern Asia, the Pacific Islands, Central Asia and Asia Minor, as well as among the Native North American and Inuit of Asian ancestry. The allele with Arg-180 is responsible for the dry earwax phenotype and lack of axillary odor. This protein has no ortholog in rodents. Belongs to the ABC transporter superfamily. ABCC family.
