DESCRIPTION

Also known as KLHL3_HUMAN, KLHL3, KIAA1129. 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 (PubMed:14528312, PubMed:22406640, PubMed:23387299, PubMed:23453970, PubMed:23576762, PubMed:23665031). The BCR(KLHL3) complex acts by mediating ubiquitination of WNK4, an inhibitor of potassium channel KCNJ1, leading to WNK4 degradation (PubMed:23387299, PubMed:23453970, PubMed:23576762, PubMed:23665031). The BCR(KLHL3) complex also mediates ubiquitination and degradation of CLDN8, a tight-junction protein required for paracellular chloride transport in the kidney (By similarity). Homodimer (PubMed:28052936). Component of the BCR(KLHL3) E3 ubiquitin ligase complex, at least composed of CUL3 and KLHL3 and RBX1 (Probable) (PubMed:23453970, PubMed:23576762, PubMed:23573258). Interacts with SLC12A3 (PubMed:22406640). Interacts with WNK1 and WNK4 (PubMed:23387299, PubMed:23453970, PubMed:23573258, PubMed:23576762, PubMed:23665031, PubMed:26435498, PubMed:27727489). Interacts with CLDN8 (By similarity).
