WNK1 is also known as [[Human accelerated regions|Human Accelerated Region]] 5. WNK1 may have played a key role in differentiating Humans from Apes. | |||
==Structure== | |||
The WNK1 protein is composed of 2382 amino acids (molecular weight 230 kDa). The protein contains a small [[N-terminus|N-terminal]] [[protein domain|domain]] followed by the kinase domain and a long [[C-terminus|C-terminal]] tail. The kinase domain has some similarity to the [[MAP kinase kinase kinase|MEKK protein kinase]] family. | |||
==Function== | |||
The WNK1 gene encodes a [[cytoplasmic]] [[serine-threonine kinase]] expressed in the [[Anatomical terms of location#Proximal and distal|distal]] [[nephron]].<ref name="entrez"/> | |||
The protein appears to be part of the [[ERK5]] [[MAP kinase]] pathway upstream of [[MAP3K2|MEKK2]] / [[MAP3K3|MEKK3]] and to function as a [[tetramer]]. It selectively binds to and [[phosphorylate]]s synaptotagmin 2 ([[SYT2]]) within its calcium-binding C2 domains. It activates the serum- and glucocorticoid-inducible protein kinase [[SGK1]], leading to activation of the [[epithelial sodium channel]]. It along with WNK4 stimulates clathrin-dependent endocytosis of renal outer medullar potassium 1 ([[ROMK|ROMK1]]). It (and [[WNK4]]) interactes with intersectin ([[ITSN1]], [[ITSN2]]). | |||
==Clinical significance== | |||
WNK1 has [[mutation]]s associated with [[Gordon hyperkalemia-hypertension syndrome]] ([[pseudohypoaldosteronism]] Type II, featuring [[hypertension]]) and [[congenital sensory neuropathy]] ([[Hereditary sensory and autonomic neuropathy|HSAN]] Type II, featuring loss of [[perception]] to [[pain]], [[touch]], and [[heat]] due to a loss of peripheral [[sensory nerve]]s).<ref name="pmid18521183">{{cite journal |vauthors=Shekarabi M, Girard N, Rivière JB, etal | title=Mutations in the nervous system--specific HSN2 exon of WNK1 cause hereditary sensory neuropathy type II | journal=J Clin Invest |date=July 2008 | volume=118 | issue=7 | pages=2496–2505 | pmid=18521183 | pmc=2398735 | accessdate=2008-11-04| doi=10.1172/JCI34088 }}</ref> ''See also:'' [[HSN2|HSN2 gene]]. | |||

WNK lysine deficient protein kinase 1, also known as WNK1, is an enzyme that in humans is encoded by the WNK1 gene.[1] The human gene is located on short arm of chromosome 12 (12p13.3).
WNK1 is also known as Human Accelerated Region 5. WNK1 may have played a key role in differentiating Humans from Apes.
Structure
The WNK1 protein is composed of 2382 amino acids (molecular weight 230 kDa). The protein contains a small N-terminal domain followed by the kinase domain and a long C-terminal tail. The kinase domain has some similarity to the MEKK protein kinase family.
Function
The WNK1 gene encodes a cytoplasmic serine-threonine kinase expressed in the distal nephron.[1]
The protein appears to be part of the ERK5 MAP kinase pathway upstream of MEKK2 / MEKK3 and to function as a tetramer. It selectively binds to and phosphorylates synaptotagmin 2 (SYT2) within its calcium-binding C2 domains. It activates the serum- and glucocorticoid-inducible protein kinase SGK1, leading to activation of the epithelial sodium channel. It along with WNK4 stimulates clathrin-dependent endocytosis of renal outer medullar potassium 1 (ROMK1). It (and WNK4) interactes with intersectin (ITSN1, ITSN2).
Clinical significance
WNK1 has mutations associated with Gordon hyperkalemia-hypertension syndrome (pseudohypoaldosteronism Type II, featuring hypertension) and congenital sensory neuropathy (HSAN Type II, featuring loss of perception to pain, touch, and heat due to a loss of peripheral sensory nerves).[2] See also: HSN2 gene.
Comparative genomics
The gene belongs to a group of four related protein kinases (WNK1, WNK2, WNK3, WNK4).
Homologs of this protein have been found in Arabidopsis thaliana, C. elegans, Chlamydomonas reinhardtii and Vitis vinifera as well as in vertebrates including Danio rerio and Taeniopygia guttata.
