From NCBI Gene:
The piggyBac family of proteins, found in diverse animals, are transposases related to the transposase of the canonical piggyBac transposon from the moth, Trichoplusia ni. This family also includes genes in several genomes, including human, that appear to have been derived from the piggyBac transposons. This gene belongs to the subfamily of piggyBac transposable element derived (PGBD) genes. The PGBD proteins appear to be novel, with no obvious relationship to other transposases, or other known protein families. [provided by RefSeq, May 2010]
Transposase that mediates sequence-specific genomic rearrangements (PubMed:26406119, PubMed:28504702). Can induce genomic rearrangements that inactivate the HPRT1 gene (PubMed:27491780).
Induces site-specific DNA rearrangements, including intrachromosomal deletions, as well as inversions, duplications and translocations, in rhabdoid tumors that share developmental origin with cells that normally express PGBD5, even though these tumors may not exhibit apparent widespread genomic instability. This activity recurrently targets regulatory elements and tumor suppressor genes and promotes cell transformation.
