  • Function

    Converts 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 specificity

    Widely expressed. High levels of expression found in brain and skeletal muscle.
  • Involvement in disease

    Defects 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 similarities

    Belongs to the tRNA pseudouridine synthase TruA family.
  • Cellular localization

    Mitochondrion and Nucleus.
