PGBD1 (PiggyBac Transposable Element Derived 1) is a human protein encoded by the PGBD1 gene, evolutionarily linked to the piggyBac transposon family found in insects. These transposons are mobile genetic elements capable of "cut-and-paste" transposition, but human PGBD1 has lost its ancestral transposase activity due to evolutionary divergence. The protein contains a conserved piggyBac transposase-like domain, though its precise molecular function remains unclear. Studies suggest potential roles in chromatin remodeling, DNA repair, or transcriptional regulation, possibly through interactions with nucleic acids or chromatin-associated proteins. Notably, PGBD1 expression is detected in the brain, testes, and immune cells, implying tissue-specific functions. Research links it to neurological disorders and cancer, with aberrant expression observed in gliomas and neurodevelopmental conditions. Recombinant human PGBD1 protein, typically produced in Escherichia coli or mammalian expression systems, enables biochemical characterization, structural studies, and interaction partner identification. Its study provides insights into the co-option of transposon-derived elements in vertebrate evolution and their potential contributions to human health and disease. However, comprehensive mechanistic understanding of PGBD1's biological significance requires further investigation.
