Insilico analysis of structural and functional impact of SNPs in Pleckstrin

Pleckstrin (PLEK) gene has been associated with a variety of disorders including autoimmune, inflammatory diseases and cancer. Mutation in this gene has been reported to be associated with autoimmune celiac disease (CD), increased atrophy in multiple sclerosis (MS), obstructive sleep apnea (OSA), abdominal aortic aneurysms, over expression in inflammatory disorders including periodontis, risk for ependymoma relapse, bladder cancer, melanoma, lung, and colorectal cancer revealing the importance of study of the PLEK. PLEK gene has been reported from other animals and therefore we have studied the molecular evolution of the PLEK gene by insilico approaches. Single nucleotide polymorphisms (SNPs), in humans have been reported to cause potential structure-function alteration in proteins. In this study we have tried to understand by insilico approaches the (i) molecular evolution of PLEK and (ii) the impact of potentially deleterious single non-synonymous SNPs (nsSNPs) on the structure and function of Pleckstrin protein. We report for the first time using molecular dynamic simulation (MDS), the impact of SNPrs17035364 and rs3816281 on the structural alterations of Pleckstrin with implications in altering its biological function which may find importance as diagnostic markers.
