Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK252-2

Antibody Target Type: Pan-specific

Protein UniProt: Q9H4A3

Protein SigNET: Q9H4A3

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human WNK1 sequence peptide Cat. No.: PE-01AYZ90

Antibody Immunogen Sequence: CLETKAVGMSNDGRFL

Antibody Immunogen Description: Corresponds to amino acid residues L207 to L221

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Antibody Concentration: 0.5 mg/ml

Storage Buffer: Phosphate buffered saline pH 7.4, 0.05% Thimerasol

Storage Conditions: For long term storage, keep frozen at -40°C or lower. Stock solution can be kept at +4°C for more than 3 months. Avoid repeated freeze-thaw cycles.

Product Use: Western blotting | Antibody microarray

Antibody Dilution Recommended: 2 µg/ml for immunoblotting

Antibody Species Reactivity: Human

Antibody Positive Control: The observed molecular mass of the processed target protein on SDS-PAGE gels is reported to be around 190, 250-400 kDa.

Scientific Background: WNK1 (PRKWNK1) is a protein-serine/threonine kinase of the Other group and WNK family. It is involved in electrolyte homeostasis, cell survival, cell signalling, and cell proliferation. It is activated by hypertonicity. The activation requires autophosphorylation of S382. Phosphorylation of S378 also promotes increased phosphotransferase activity. WNK1 can activate sodium-coupled chloride cotransporters, and inhibit potassium-coupled chloride cotransporters. Proteins activated by WNK1 include SCNN1A, SCNN1B, SCNN1D and SGK1 while an inhibited protein is WNK4 (via phosphorylation of WNK4 or an associated complex of a WNK1 autoinhibitory domain bound to WNK4). WNK4 inhibition could modulate, via phosphorylation, a thiazide-sensitive NaCl cotransporter transporter (specifically SLC12A3). WNK1 has also been proposed to modulate NEDD4L phosphorylation, and have an effect on actin cytoskeleton rearrangement. Insertional mutagenesis studies in mice support a role for this protein kinase in mouse cancer oncogenesis.
