Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK255-3

Antibody Target Type: Pan-specific

Protein UniProt: Q96J92

Protein SigNET: Q96J92

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human WNK4 (PRKWNK4) sequence peptide Cat. No.: PE-01AZJ99
Antibody Immunogen Sequence: CRASKGVTFAGDVGRM

Antibody Immunogen Description: Corresponds to amino acid residues R1229 to M1243; C-terminus

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.

Scientific Background: WNK4 (PRKWNK4) is a protein-serine/threonine kinase of the Other group and WNK family. It regulates electrolyte homeostasis. WNK4 can activate the genes SCNN1A, SCNN1B, SCNN1D, SGK1, TRPV5 and TRPV6. The renal potassium channel KCNJ1, through a kinase-mediated mechanism, will be inhibited via clathrin-mediated receptor endocytosis. WNK4 can also phosphorylate NEDD4L. Activation of WNK4 requires autophosphorylation of S335. Phosphorylation of S331 also promotes increased activity.
