Shukla V, Srivatsa K, Madhu Kumar M, Vajpai N, Agarwal N, Nethra S, et al.
Protein Expr Purif . 2021 May; 185:105895. PMID: 33957255
Biopharmaceutical development demands appropriate understanding of product related variants, which are formed due to post-translational modification and during downstream processing. These variants can lead to low yield, reduced biological activity,...

Vo U, Vajpai N, Embrey K, Golovanov A
Sci Rep . 2016 Jul; 6:29706. PMID: 27412770
The cycling between GDP- and GTP- bound forms of the Ras protein is partly regulated by the binding of Sos. The structural/dynamic behavior of the complex formed between activated Sos...

Klein T, Vajpai N, Phillips J, Davies G, Holdgate G, Phillips C, et al.
Nat Commun . 2015 Jul; 6:7877. PMID: 26203596
Protein tyrosine kinases differ widely in their propensity to undergo rearrangements of the N-terminal Asp-Phe-Gly (DFG) motif of the activation loop, with some, including FGFR1 kinase, appearing refractory to this...
