| + | [[http://www.uniprot.org/uniprot/KLHL3_HUMAN KLHL3_HUMAN]] Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complex that acts as a regulator of ion transport in the distal nephron. The BCR(KLHL3) complex acts by mediating ubiquitination of WNK4, an inhibitor of potassium channel KCNJ1, leading to WNK4 degradation.<ref>PMID:14528312</ref> <ref>PMID:23387299</ref> <ref>PMID:23453970</ref> <ref>PMID:23665031</ref> <ref>PMID:23576762</ref> <ref>PMID:22406640</ref> [[http://www.uniprot.org/uniprot/WNK3_HUMAN WNK3_HUMAN]] Serine/threonine kinase which plays an important role in the regulation of electrolyte homeostasis, cell signaling, survival and proliferation. Acts as an activator and inhibitor of sodium-coupled chloride cotransporters and potassium-coupled chloride cotransporters respectively (PubMed:16275913, PubMed:16275911, PubMed:16357011). Phosphorylates WNK4. Regulates the phosphorylation of SLC12A1 and SLC12A2. Increases Ca(2+) influx mediated by TRPV5 and TRPV6 by enhancing their membrane expression level via a kinase-dependent pathway (PubMed:18768590). Inhibits the activity of KCNJ1 by decreasing its expression at the cell membrane in a non-catalytic manner.<ref>PMID:16275911</ref> <ref>PMID:16275913</ref> <ref>PMID:16357011</ref> <ref>PMID:16501604</ref> <ref>PMID:17975670</ref> <ref>PMID:18768590</ref> <ref>PMID:20525693</ref> Isoform 1, isoform 2, isoform 3 and isoform 4 stimulate the activity of SLC12A1, SLC12A2 and SLC12A3 and inhibit the activity of SLC12A4, SLC12A5, SLC12A6 and SLC12A7. According to PubMed:19470686, isoform 1 inhibits the activity of SLC12A3.<ref>PMID:19470686</ref> <ref>PMID:21613606</ref> | ||
