  • FunctionConverts specific uridines to PSI in a number of tRNA substrates. Acts on positions 27/28 in the anticodon stem and also positions 34 and 36 in the anticodon of an intron containing tRNA. Involved in regulation of nuclear receptor activity possibly through pseudouridylation of SRA1 RNA.
  • Tissue specificityWidely expressed. High levels of expression found in brain and skeletal muscle.
  • Involvement in diseaseDefects in PUS1 are a cause of myopathy with lactic acidosis and sideroblastic anemia type 1 (MLASA1) [MIM:600462]; also known as mitochondrial myopathy and sideroblastic anemia. MLASA is a rare autosomal recessive oxidative phosphorylation disorder specific to skeletal muscle and bone marrow.
  • Sequence similaritiesBelongs to the tRNA pseudouridine synthase TruA family.
  • Cellular localizationMitochondrion and Nucleus.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian carcinoma tissue labelling PUS1 with ab85938 at 1/1000 (0.2µg/ml). Detection: DAB.
  • All lanes : Anti-PUS1 antibody (ab85938) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg

    developed using the ECL technique

    Predicted band size : 47 kDa
    Observed band size : 47 kDa

    Exposure time : 10 seconds
    Note: there are two isoforms of this protein, the second missing amino acids 1-28, which could explain the presence of a double band.
  • Detection of human PUS1 in immunoprecipitates of whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded), using ab85938 at 3 µg/mg lysate for IP, and at 1 µg/ml for subsequent Western blot.

    Detection: Chemiluminescence with an exposure time of 10 seconds.
    Note: there are two isoforms of this protein, the second missing amino acids 1-28, which could explain the presence of a double band.
