This gene is ubiquitously expressed and encodes a full-length protein which has an N-terminal BTB domain followed by a BACK domain and six kelch-like repeats in the C-terminus. These kelch-like repeats promote substrate ubiquitination of bound proteins via interaction of the BTB domain with the CUL3 (cullin 3) component of a cullin-RING E3 ubiquitin ligase (CRL) complex. Muatations in this gene cause pseudohypoaldosteronism type IID (PHA2D); a rare Mendelian syndrome featuring hypertension, hyperkalaemia and metabolic acidosis. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Mar 2012] (from

Mutations in WNK1 and WNK4, and in components of the Cullin-Ring Ligase system, kelch-like 3 (KLHL3) and Cullin 3 (CUL3), can cause the rare hereditary disease, Familial Hyperkalemic Hypertension (FHHt).

We reported that kelch-like protein 3 (KLHL3)-Cullin3 E3 ligase ubiquitinates with-no-lysine kinase 4 (WNK4) and that impaired WNK4 ubiquitination causes pseudohypoaldosteronism type II, a hereditary hypertensive disease.
Pseudohypoaldosteronism type II (PHAII) is a hereditary hypertensive disease caused by mutations in four different genes: with-no-lysine kinases (WNK) 1 and 4, Kelch-like family member 3 (KLHL3), and cullin 3 (Cul3).
Uchida, Tokyo, Japan. In Curr Opin Nephrol Hypertens, 2014
We here discuss a novel pathogenic mechanism underlying the hereditary hypertensive disease pseudohypoaldosteronism type II (PHAII), caused by mutations in three different genes encoding for Cullin-3, Kelch-like protein 3 (KLHL3), and with-no-lysine kinases (WNKs).
Pedraza-Chaverri et al., Mexico. In Cell Signal, 2014
Recently, Cul3 has been linked to the development of type II pseudohypoaldosteronism (PHAII or Gordon's syndrome) due to the fact that Cul3 has the ability to bind to Kelch-like 3 protein (KLHL3) and therefore mediating the degradation of some members of the WNK kinases.
Jeunemaitre et al., Paris, France. In Nat Genet, 2012
identified KLHL3 as a third gene responsible for familial hyperkalemic hypertension; study establishes a role for KLHL3 as a new member of the complex signaling pathway regulating ion homeostasis in the distal nephron and indirectly blood pressure
