    Text During mouse early embryogenesis Osr1 is expressed in the intermediate mesoderm and in a dynamic pattern during limb and branchial arch development
  • restricted to the central dorsal domain of the mouse atrial myocardium during normal heart development
  • three C2H2-type zinc fingers, a tyrosine phosphorylation site (Tyr 203), and several putative PXXP SH3 binding motifs
  • kinase domain (aa17291); PF1 domain (aa292344), with the putative caspase 3 recognized sequence DEFD at the end (aa434527), PF2 domain
  • PF1 domain is essential for OSR1 kinase activity

    basic FUNCTION
  • plays an important role in establishing kidney precursor cells, and in regulating their differentiation into kidney tubular tissue
  • required to limit endoderm differentiation from mesendoderm
  • zinc finger transcription factor
  • playing important roles in embryonic heart and urogenital development
  • OSR1 and OSR2 function is required for maintenance of expression of signaling molecules critical for joint formation, including GDF5, WNT4 and WNT9B
  • OSR1 and OSR2 function redundantly to control synovial joint formation
  • STK39 and OSR1 may be critical factors in the regulation of depolarizing GABA-mediated processes in the developing brain
  • involved in SLC12A3 phosphorylation with SPAK kinases
  • STK39 and OSR1 regulate sodium-chloride co-transporters SLC12A3, and SLC12A1 in a nephron-specific manner
  • STK39 and OSR1 associate with membranes as peripheral proteins and exhibited distinct subcellular and region-specific expression profiles throughout the lens
  • CELLULAR PROCESS nucleotide, transcription
    PHYSIOLOGICAL PROCESS electron transport
    a component
    small molecule metal binding,
  • ion Zn2+ binding
  • protein
  • WNK1 affects ion transport in part through activation of OSR1 and STK39
  • WNK1 activation of the OSR1 signaling cascade is likely an essential pathway that regulates angiogenesis and cardiac formation during development
  • separation of functions for the WNK1-activated protein kinases OSR1 and STK39 in mediating proliferation, invasion, and gene expression in endothelial cells and an unanticipated link between WNK1 and SNAI2 that is important for angiogenesis
  • both, STK39 and OSR1, are negative regulators of the creatine transporter SLC6A8
  • WNK1 and WNK4 are the targets for the KLHL3-CUL3 complex and modulate the activity of SLC12A5 by means of intermediary Ste20-type kinases known as STK39 or OSR1

    Candidate gene
    Therapy target
  • Odd 1(-/-) mutant mouse embryos fail to form atrial septum, display dilated atria with hypoplastic venous valves, and exhibit blood backflow from the heart into systemic veins
  • homozygous Odd 1(-/-) mutant mouse embryos exhibit complete agenesis of adrenal glands, metanephric kidneys, gonads, and defects in pericardium formation
  • Knockdown of osr1 in zebrafish embryos resulted in a complete, segment-specific loss of anterior kidney progenitors and a compensatory increase in the number of angioblast cells in the same trunk region
  • Osr1(-/-) mutant mice died at midgestation
