Chemical compound and disease context of OXSR1

 

Biological context of OXSR1

  • The residues on NKCC1, phosphorylated by SPAK/OSR1, are conserved in other cation co-transporters, such as the Na+-Cl- co-transporter, the target of thiazide drugs that lower blood pressure in humans with Gordon's syndrome [7].
  • Genetic analysis suggests that OSR1 evolved first, with SPAK arising following a gene duplication in vertebrate evolution [8].
  • SPAK and OSR1 are two recently discovered kinases which have been linked to several key cellular processes, including cell differentiation, cell transformation and proliferation, cytoskeleton rearrangement, and most recently, regulation of ion transporters [8].
  • Based on the alignment of 12 sequences of protein motifs that interact with the kinases SPAK (Ste20-related proline alanine-rich kinase) and OSR1 (oxidative stress response 1), we performed genome-wide searches of the sequence [S/G/V]RFx[V/I]xx[V/I/T/S]xx, where x represents any amino acid [9].
  • Taken together, we propose that human Ngb may be a novel oxidative stress-responsive sensor for signal transduction in the brain [10].
 

Anatomical context of OXSR1

 

Associations of OXSR1 with chemical compounds

 

Regulatory relationships of OXSR1

  • We have identified specific residues within the CCT domain that are required for interaction with the RFXV motif and have demonstrated that mutation of these in OSR1 inhibited phosphorylation of NKCC1, but not of CATCHtide which does not possess an RFXV motif [7].
