P-element Mediated Transgenesis Service

P-elements are mobile genetic elements found in the genome of Drosophila species. They were initially discovered in the 1970s and have since revolutionized the field of genetics and transgenesis. This transposition mechanism allows researchers to precisely introduce new genes or modify existing ones in Drosophila, enabling a wide range of genetic studies and functional analyses. CD BioSciences is a global research company focused on Drosophila scientific solutions. Based on our cutting-edge Drosophila transformation technology platform, we offer customized P-element mediated transgenic services to address technical challenges in the Drosophila transgenics field.

Mechanism and Regulation of P-element Transposition

P-elements encode an enzyme, a transposase that is responsible for mobilizing the P-element DNA. While the specifics of transposition vary among DNA transposon families, the general process involves six essential steps transposase-transposon DNA binding, the pairing of the transposon ends (synaptic complex formation), donor DNA cleavage, target DNA capture, strand transfer (integration) and disassembly/DNA repair.

Similar to other DNA transposons, the P-element transposase initially binds to specific sites on the transposon. Once it recognizes one transposon end, the P-element transposase, dependent on GTP, captures and pairs the second end, creating a paired-end complex. Sequential cleavage of each P-element end releases the transposon from the surrounding host genome, resulting in the formation of the cleaved donor complex.

After donor DNA cleavage, the excised transposon-transposase nucleoprotein complex captures a target DNA and integrates the P-element. The mechanisms of disassembly and DNA repair at the target site remain unknown. However, it is understood that the double-strand break generated at the donor site can be repaired through either the homologous recombination-dependent (HR) pathway or the non-homologous end joining (NHEJ) pathway of DNA repair.
