      Background InformationSTE20/SPS-1 related proline alanine-rich kinase (SPAK), or commonly known as Serine/threonine-protein kinase 39, is a member of the SPS1 subfamily of STE20 kinases. Serine/threonine-protein kinase 39 is also very highly conserved between species and has been shown to activate the p38 pathways. Serine/threonine-protein kinase 39 also has a caspase cleavage site and these two functions may mean that Serine/threonine-protein kinase 39 plays a role in stress-activated signaling. Serine/threonine-protein kinase 39 expression is up-regulated by androgens in LNCaP human prostate cancer cells and regulated and phosphorylated by WNK1, which controls the stress signaling pathway. It is activated by WNK4 and then has the ability to stimulate the Na-K-2Cl cotransporter, the inactive version does not posses this ability. Recent research has also made a connection between Serine/threonine-protein kinase 39 and regulation of blood pressure.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a serine/threonine kinase that is thought to function in the cellular stress response pathway. The kinase is activated in response to hypotonic stress, leading to phosphorylation of several cation-chloride-coupled cotransporters. The catalytically active kinase specifically activates the p38 MAP kinase pathway, and its interaction with p38 decreases upon cellular stress, suggesting that this kinase may serve as an intermediate in the response to cellular stress.
