CC -!- FUNCTION: Pore-forming subunit of a potassium efflux system that
CC confers protection against electrophiles. Catalyzes K(+)/H(+) antiport.
CC Can also export rubidium, lithium and sodium. {ECO:0000255|HAMAP-
CC Rule:MF_01413, ECO:0000269|PubMed:17679694,
CC ECO:0000269|PubMed:21041667, ECO:0000269|PubMed:9023177}.
CC -!- ACTIVITY REGULATION: Inhibited by glutathione. This inhibition is
CC increased by NADH. Activated by adducts between glutathione and
CC electrophiles. {ECO:0000269|PubMed:17679694,
CC ECO:0000269|PubMed:21041667, ECO:0000269|PubMed:9023177}.
CC -!- SUBUNIT: Homodimer. Interacts with the regulatory subunit KefF, forming
CC a heterotetramer with 2:2 stoichiometry. Interaction with KefF is
CC required for optimal activity. The active antiporter may be formed by
CC the heterotetramer, or by an octamer. {ECO:0000255|HAMAP-Rule:MF_01413,
CC ECO:0000269|PubMed:17679694, ECO:0000269|PubMed:19523906,
CC ECO:0000269|PubMed:21041667}.
CC -!- INTERACTION:
CC P03819; P0A754: kefF; NbExp=2; IntAct=EBI-547193, EBI-562116;
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01413, ECO:0000269|PubMed:15919996,
CC ECO:0000269|PubMed:2046548}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_01413, ECO:0000269|PubMed:15919996,
CC ECO:0000269|PubMed:2046548}.
CC -!- DOMAIN: The cytoplasmic RCK N-terminal domain regulates channel
CC activity. It binds glutathione, resulting in inhibition of potassium
CC efflux. In contrast, binding of the adducts formed between glutathione
CC and electrophiles leads to activation of potassium efflux. Is expected
CC to bind NADH, but X-ray crystallography shows bound AMP, and it would
CC be difficult to accommodate NADH in this binding site
CC (PubMed:21041667). {ECO:0000269|PubMed:21041667}.
CC -!- SIMILARITY: Belongs to the monovalent cation:proton antiporter 2 (CPA2)
CC transporter (TC 2.A.37) family. KefC subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01413}.
