WNK4 Antibody, FITC conjugated

1. 5 WNK4 sites (S47, S64, S1169, S1180, S1196) are phosphorylated downstream of AngII signaling in cultured cells and in vitro by PKC and PKA. Phosphorylation at S64 and S1196 promoted phosphorylation of the WNK4 kinase T-loop at S332 (required for kinase activation) and increased phosphorylation of SPAK.

18. Data show that K1169E lost its inhibitory effect on NCC surface expression compared to wild-type WNK4 when expressed in HEK293 cells, while it did not change NCC total protein expression. PMID: 21196779
19. Results show that Tyr512 phosphorylation is a novel signal regulating the prevalence of CFTR at the cell surface and that WNK4 and Syk perform an antagonistic role in this process. PMID: 21807898
