Target Background

May act as a mediator of stress-activated signals. Mediates the inhibition of SLC4A4, SLC26A6 as well as CFTR activities by the WNK scaffolds, probably through phosphorylation. Phosphorylates RELT.

  10. SPAK protein has both the potential to up-regulate KCNQ1/E1 protein abundance in the cell membrane, an effect possibly participating in the regulation of cell volume, excitability, epithelial transport and metabolism. PMID: 26584301
  11. These observations establish that the CCT domain plays a crucial role in controlling SPAK activity and BP. PMID: 25994507
  12. Findings indicate that the serine threonine kinase 39 (STK39) mRNA expression is increased in rs3754777 knockin cell lines. PMID: 26416847
  13. These findings suggested that the STK39 rs1955337 TT genotype is a risk factor for Han-Chinese patients with PD in Taiwan PMID: 26469904
  14. Taken together, our findings suggest the potential interactive role of STK39 gene multiple polymorphisms in the development of hypertension among northeastern Han Chinese. PMID: 24873805
