24393035 the WNK-regulated SPAK/OSR1 kinases directly phosphorylate the N[K]CCs and KCCs, promoting their stimulation and inhibition respectively.
23034389 SPAK and OSR1, which are often coexpressed in cells, can form functional heterodimers.
22989884 Data show that intracellular association between WNK1 and oxidative stress-responsive 1 (OSR1) is required for stimulation of OSR1 and Na(+), K(+), Cl(-)-Cotransporter NKCC1 and NKCC2 activities by osmotic stress.
20889219 Observational study of gene-disease association. (HuGE Navigator)
20819979 OXSR1 and WNK3 transcripts were substantially overexpressed in subjects with schizophrenia relative to comparison subjects.
19177573 crystal structure of OSR1 kinase domain has been solved at 2.25 A; OSR1 forms a domain-swapped dimer in an inactive conformation, in which P+1 loop and alphaEF helix are swapped between dimer-related monomers
18831043 The first crystal structure of an OSR1 fragment encompassing the catalytic domain of the enzyme, is reported.
18270262 The WNK1-SPAK/OSR1 signalling pathway plays a key role in controlling the phosphorylation and activity of NCC.
17721439 These results provide the first molecular insight into the mechanism by which the SPAK and OSR1 kinases specifically recognize their upstream activators and downstream substrates.
16832045 OSR1 and sterile20-related, proline-, alanine-rich kinase are likely links between WNK lysine deficient protein kinase 1 and solute carrier family 12 in a pathway that contributes to volume regulation and blood pressure homeostasis in mammals
16669787 data establish that the CCT domain functions as a multipurpose docking site, enabling SPAK/OSR1 to interact with substrates (NKCC1) and activators (WNK1/WNK4)
16389068 OXSR1 kinase is shown to interact with the three RELT family members RELT, RELL1, and RELL2 by in vitro co-immunoprecipitation; additionally, OXSR1 phosphorylates RELT family members in an in vitro kinase assay.
16263722 WNK1 and SPAK/OSR1 mediate the hypotonic stress signaling pathway to cation-chloride-coupled cotransporters
14707132 isolation and characterization of OSR1 (oxidative stress-responsive 1), one of two human Fray homologs. OSR1 is a 58-kDa protein of 527 amino acids that is widely expressed in mammalian tissues and cell lines
12386165 interacts with cation chloride cotransporters
