Anti-pseudouridine synthase like 1 antibodies are used for the immunodetection of the protein encoded by the PUSL1 gene. In humans, the canonical protein has a reported length of 303 amino acid residues and a mass of 33.2 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the TRNA pseudouridine synthase TruA protein family. Other names for this target antigen include pseudouridylate synthase like 1, tRNA pseudouridylate synthase-like 1, tRNA-uridine isomerase-like 1, and tRNA pseudouridine synthase-like 1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
