Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including intracellular chloride ion homeostasis; negative regulation of transport; and protein phosphorylation. Acts upstream of or within monoatomic ion homeostasis; regulation of blood pressure; and regulation of inflammatory response. Located in basolateral plasma membrane. Is active in apical plasma membrane and cell body. Is expressed in brain and metanephros. Used to study Gitelman syndrome and pseudohypoaldosteronism. Orthologous to human STK39 (serine/threonine kinase 39). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Broad expression in testis adult (RPKM 29.2), cerebellum adult (RPKM 12.7) and 19 other tissues See more

Study shows that in the absence of aspartyl aminopeptidase (DNPEP), the kidney lysates retain their ability to cleave STE20/SPS1-related proline/alanine-rich kinase(SPAK), indicating that DNPEP might have been misidentified as the protease behind the kidney lysate activity, or that the aspartyl aminopeptidase might not be the only protease cleaving SPAK in kidney.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
