WNK1 [with no lysine (K)-1] is a 250-kDa serine/threonine protein kinase involved in the maintenance of cellular salt levels and is directly linked to a hereditary form of hypertension. Here, we report the solution NMR structure of the autoinhibitory domain of WNK1 (WNK1-AI), a small regulatory subunit that lies immediately C-terminal of the kinase domain. We show that this domain is a homolog of the RFXV-binding PASK/FRAY homology 2 (PF2) domain found in OSR (oxidative stress responsive kinase) and SPAK (serine/threonine proline-alanine-rich kinase) kinases, which are substrates of WNK1. The WNK1-AI has a circularly permuted topology relative to the OSR1-PF2 domain. Nevertheless, like PF2 domains, WNK1-AI binds peptides that contain an RFXV motif with micromolar affinities as assessed by changes in (1)H,(15)N heteronuclear single quantum coherence spectra. Mutations to the WNK1-AI and binding peptides confirm a similar binding mode.

[[http://www.uniprot.org/uniprot/WNK1_RAT WNK1_RAT]] 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. Activates SCNN1A, SCNN1B, SCNN1D and SGK1. Controls sodium and chloride ion transport by inhibiting the activity of WNK4, by either phosphorylating the kinase or via an interaction between WNK4 and the autoinhibitory domain of WNK1. WNK4 regulates the activity of the thiazide-sensitive Na-Cl cotransporter, SLC12A3, by phosphorylation. WNK1 may also play a role in actin cytoskeletal reorganization. Phosphorylates NEDD4L.<ref>PMID:17975670</ref> <ref>PMID:20525693</ref>
