Anti-pseudouridine synthase 7 antibodies are used for the immunodetection of the protein encoded by the PUS7 gene. In humans, the canonical protein has a reported length of 661 amino acid residues and a mass of 75 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Pseudouridine synthase TruD protein family, it is reported to be a pseudouridylate synthase that catalyzes pseudouridylation of RNAs. The gene encoding this protein is implicated in Intellectual developmental disorder with abnormal behavior, microcephaly, and short stature. Other names for this target antigen include pseudouridylate synthase 7 homolog, pseudouridylate synthase 7 (putative), and IDDABS. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
