Single-nucleotide polymorphisms (SNPs) play a major role in the understanding of the genetic basis of many complex human diseases. Also, the genetics of human phenotype variation could be understood by knowing the functions of these SNPs. It is still a major challenge to identify the functional SNPs in a disease-related gene. In this work, we have analyzed(More)
Single Nucleotide Polymorphisms (SNPs) are being intensively studied to understand the biological basis of complex traits and diseases. The Genetics of human phenotype variation could be understood by knowing the functions of SNPs. In this study using computational methods, we analyzed the genetic variations that can alter the expression and function of the(More)
In this work, we identified the detrimental missense mutations (point mutations) in epidermal growth factor receptor (EGFR) and its binding efficiency with the inhibitors namely Erlotinib, Gefitinib, and Lapatinib. Out of 26 point mutations on EGFR, 12 point mutations were commonly less stable, deleterious, and damaged as shown by all the three servers,(More)
Structural stability of Oldenlandia affinis cyclotide, kalata B1 of native (1NB1) and two mutants 2F2I ([P20D, V21K] kB1) and 2F2J ([W19K, P20N, V21K] kB1) was investigated. Single model analysis showed high number of intra-molecular interactions followed by more proportion of beta sheet contents in [P20D, V21K] kB1 as compared to that of native and the(More)
In this study, we identified the most deleterious non-synonymous SNP of ERBB2 (HER2) receptors by its stability and investigated its binding affinity with herceptin. Out of 135 SNPs, 10 are nsSNPs in the coding region, in which one of the nsSNP (SNPid rs4252633) is commonly found to be damaged by I-Mutant 2.0, SIFT and PolyPhen servers. With this effort, we(More)
Oseltamivir (Tamiflu) is the preferred anti-viral drug employed to fight the flu virus in infected individuals. The principal target for this drug is a virus surface glycoprotein, neuraminidase (NA), which facilitates the release of nascent virus and thus spreads infections. Until recently, only a low prevalence of neuraminidase inhibitors (NAIs) resistance(More)
The recent H1N1 influenza pandemic has attracted worldwide attention due to the high infection rate. Oseltamivir is a new class of anti-viral agent approved for the treatment and prevention of influenza infections. The principal target for this drug is a virus surface glycoprotein, neuraminidase (NA), which facilitates the release of nascent virus and thus(More)
In this work, we computationally identified the most detrimental missense mutations of KIT receptor causing gastrointestinal stromal tumors and analyzed the drug resistance of these missense mutations. Out of 31 missense mutations, 19 variants were commonly found less stable, deleterious and damaging by I-Mutant 2.0, SIFT and PolyPhen programs,(More)
We have investigated and highlighted the behavior of binding residue, Asp25 by computational analysis, which play an important role in understanding docking process with drug molecule, Ritonavir (Norvir) and the flexibility nature of the Human Immunodeficiency Virus-1 (HIV-1) protease enzyme. It is well known that Ritonavir is a potent and a selective HIV-1(More)
In this study, we identified the most deleterious nsSNP in CDKN2A gene through structural and functional properties of its protein (p16INK4A) and investigated its binding affinity with cdk6. Out of 118 SNPs, 14 are nsSNPs in the coding region and 17 SNPs were found in the untranslated region (UTR). FastSNP suggested that 7 SNPs in the 5' UTR might change(More)
