Activated by N-ethylmaleimide (NEM) (PubMed:10600773). Inhibited by DIOA, bumetanide and furosemide (PubMed:10600773).BIOPHYSICOCHEMICAL PROPERTIES Homodimer (PubMed:21628467). Homomultimer and heteromultimer with other K-Cl cotransporters (Probable). Interacts (via C-terminus) with CKB; the interaction may be required for potassium-chloride cotransport activity (PubMed:18566107).SUBCELLULAR LOCATION Expressed in brain (at protein level) (PubMed:21628467). Highly expressed in heart, brain and kidney. Detected at lower levels in skeletal muscle, placenta, lung and pancreas (PubMed:10600773). Detected in umbilical vein endothelial cells (PubMed:16048901).TISSUE SPECIFICITY More abundant in kidney.TISSUE SPECIFICITY Testis specific.INDUCTION Up-regulated by VEGF. Down-regulated by TNF.DOMAIN N-terminal loop binds to the intracellular vestibule of the transporter, arresting the transporter in an inhibited state.PTM Phosphorylated, phosphorylation regulates transporter activity (PubMed:34031912, PubMed:19665974, PubMed:21613606). Phosphorylated at Thr-991 and Thr-1048 by OXSR1/OSR1 and STK39/SPAK downstream of WNK kinases (WNK1, WNK2, WNK3 or WNK4), inhibiting the potassium-chloride cotransport activity (PubMed:19665974, PubMed:21613606).PTM N-glycosylated.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS Produced by alternative promoter usage.MISCELLANEOUS Does not differ in the osmotic set point of swelling activation but, activation is more rapid.MISCELLANEOUS Does not differ in the osmotic set point of swelling activation but, activation is more rapid.SIMILARITY Belongs to the SLC12A transporter family.
