Molecular cloning and 3D structure modeling of APEX1, DNA base excision repair enzyme from the Camel, Camelus dromedarius.

ABSTRACT: The domesticated one-humped camel, Camelus dromedarius, is one of the most important animals in the Arabian Desert. It is exposed most of its life to both intrinsic and extrinsic genotoxic factors that are known to cause gross DNA alterations in many organisms. Ionic radiation and sunlight are known producers of Reactive Oxygen Species (ROS), one of the causes for DNA lesions. The damaged DNA is repaired by many enzymes, among of them Base Excision Repair enzymes, producing the highly mutagenic apurinic/apyrimidinicsites (AP sites). Therefore, recognition of AP sites is fundamental to cell/organism survival. In the present work, the full coding sequence of a putative cAPEX1 gene was amplified for the first time from C. dromedarius by RT-PCR and cloned (NCBI accession number are HM209828 an
