The spike (S) protein is a major antigenicity site that targets neutralizing antibodies and drugs. growing number of S mutations has become severe problem for developing effective vaccines. Here, we investigated four acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants were the most infectious widespread during COVID-19 pandemic to determine trends patterns mutation-induced changes in...

Human serum albumin (HSA) is the most abundant plasma protein in the human body. HSA plays an important role in drug transport and metabolism. This protein has a high affinity to a very wide range of materials, including metals such as Cu2+ and Zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. In this study, we investigated the effects of co-amoxiclav, as...

The coronavirus disease-2019 (COVID-19) pandemic, caused by the pathogen severe acute respiratory syndrome 2 (SARS-CoV-2), started in China during late 2019 and swiftly spread worldwide. Since COVID-19 emergence, many therapeutic regimens have been relentlessly explored, although two vaccines just received emergency use authorization different governmental agencies, antiviral therapeutics based...

March 2020 marked the beginning of a global pandemic caused by SARSCoV- 2. With development, production and distribution several vaccines there are hopes to an end in sight. However, with emergence mutated viral strains concerns mounting as effectiveness current treatments preventative measures against new strains. Herein we analyzed compared interaction SARS-CoV-2 Spike (S) protein its variant...

the genetic polymorphism of some genes related to meat production in three egyptian sheep breeds (barki, rahmani and osseimi) was studied. the candidate genes were: calpastatin, myostatin, diacylglycerol-acyltransferase1, insulin-like growth factor binding protein-3 and booroola fecundity gene. the technique applied was the restriction fragment length polymorphism for the polymerase chain react...

ALG-2 was originally discovered as a pro-apoptotic protein in a genetic screen. Due to its ability to bind calcium with high affinity it was postulated to provide a link between the known effect of calcium in programmed cell death and the molecular death execution machinery. This review article discusses the current knowledge on the structure and potential function of this protein. Several puta...

Lactoferrin (Lf) is an iron-binding multi-functional glycoprotein which has numerous physiological functions such as iron transportation, anti-microbial activity and immune response. In this study, different in silico approaches were exploited to investigate Lf protein properties in a number of mammalian species. Results showed that the iron-binding site, DNA and RNA-binding sites, signal pepti...
