Disease
KLHL3_HUMAN Pseudohypoaldosteronism type 2D. The disease is caused by mutations affecting the gene represented in this entry.
Function
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.[1] [2] [3] [4] [5] [6]
