The labdevelops PAT technology for recombinant therapeutic proteins and value addedcompounds such as biopolymers, organic acids etc. PAT is defined as 'System fordesigning (process development), analysing and controlling manufacturingprocess, based on timely measurements of critical quality and performanceattributes of raw material, in process materials and processes with the goal ofensuring final product quality'. PAT methodology envisages the identificationof Critical Process Parameters (CPPs) and Critical Quality Attributes (CQAs)for every process. The CPPs are the indication of the overall reliability thata process proceed in the desired direction. Therefore their monitoring and controlestablishes the uniform product quality. 'Quality by design' in the PATemphasizes that monitoring to be accomplished not only during the process, butshould begin from raw material characterization, its processing, upstreamprocess, product recovery, downstream process and till the polishing step.Therefore this reduces the much effort emphasized by regulatory authorities onensuring quality.

The lab’sresearch interest is in post-translational gene regulation by RNA bindingproteins. During alternative splicing introns are splicedout in various ways from the precursor RNA, resulting in one gene producingseveral different mRNAs and protein products. The process of alternativesplicing requires accurate selection of splice sites, which play a key factorin the generation of different transcripts. Several regulatory proteincomplexes take active part to aid in the selection of splice sites, like smallnuclear ribonucleoprotein complexes containing U1, U2, U4/U6 and U5 subunits.The serine/arginine-rich protein family members (SR proteins) and SR-relatedproteins (SR-rps) also have the capability to assist in the splice siteselection process. In addition, various other regulatory protein complexesmight be involved in the alternative splicing process. In this regard,understanding the role of the subunits existing in the apoptosis and splicingassociated protein (ASAP) complex during splice site selection are crucial tounderstand splicing dependent post-transcriptional steps of gene regulation.

The tree species with long generation cycle aremostly highly heterozygous in nature due to strict cross pollination and areconsidered to be recalcitrant (difficult to regenerate in vitro). The geneticimprovement of these plants and development of homozygous lines (pure) iseither very challenging or impossible using the conventional methods, becausethe cross pollination is a rule. This limitation has completely been overcomeby the research group of Dr Chaturvedi while working on two complex treespecies, Neem (Azadirachta indica) and Tea (Camellia species).Prof. Chaturvedi’s laboratory has alsoinvolved in developing Plant Cell Culture Technology as an alternative to wholeplant extraction for the production of secondary metabolites of medicinal andcommercial values. Although these compounds can also be isolated from naturallygrown whole plants, continued destruction of plants for the purpose may pose amajor threat to species getting extinct. Her research group is able toidentify, purify and isolate three main categories of bioactive metabolites:essential oils, coumarins and alkylamides, from in vitro elite cell lines ofmedicinal plants. Some of these compounds are complex triterpenoids which aredifficult to synthesize chemically.
