Bose Laboratory is focused on study of macromolecules involved in the apoptotic pathway and their implications in normal cellular functions and pathogenesis. The lab works on high temperature requirement family of serine proteases (HtrA); interaction between antiapoptotic c-FLIP and calmodulin; Bcl2 family proteins and their interacting partners. Moreover, the laboratory is entering into application-based translational research that includes enzymes involved in metabolic reprogramming and their role in altering cancer signaling pathway. Dr. Bose organized the Indo-US conference/workshop on 'Advances in Enzymology' in January 2017.

    Research focused on macromolecules involved in alternate pathways of apoptosis and their associated diseases





Highlights of the research findings at Bose Lab include elucidation of the structural basis of HtrA2 mutations that are implicated in diseased phenotypes. Crystallography data of one such mutants has been deposited in Protein Data Bank (PDB ID: 5WYN). The laboratory has made several important discoveries such as mode of interaction of HtrA2 with its natural substrate, identification of a novel binding partner as well as design of its promising inhibitors. These crucial pieces of information would provide means to manipulate HtrA2 with desired characteristics. The laboratory has developed a database comprising PDZ-domain containing proteins ‘PDZscape’, which is freely available to the users worldwide.

Investigating the molecular basis of CaM/c-FLIP interaction to design specific c-FLIP inhibitor for modulating its antiapoptotic function

With the information that Fas-mediated apoptosis and tumorigenesis are influenced by CaM/c-FLIP (oncoprotein) interaction, we aim at developing specific inhibitors that target the binding pocket of c-FLIP and thereby CaM/c-FLIP association.

Biophysics Facility


The ACTREC Biophysics facility houses an extensive array of sophisticated instruments for in vitro molecular-scale characterization of biological macromolecules with accuracy and precision. The facility provides services to different projects, enabling the characterization of the intrinsic properties of macromolecules and their assemblies (size, shape, folding and stability) and of the interactions in which they are involved (stoichiometry, thermodynamic and kinetic parameters). Biophysics facility is equipped with Jasco J-815 Circular Dichroism Spectropolarimeter, FluroLog -3 Modular Spectrofluorimeter, Dynamic Light Scattering (DLS) DynaPro Plate Reader II, BIAcore T200 for automated surface plasmon resonance (SPR), and MicroCal iTC200 isothermal titration calorimeter (ITC). Along with technically sound instrumentation, ACTREC biophysics facility also provides expertise to assist the users in experimental design and data interpretation, if required. Depending on individual requirements, either experiment can be performed for the users or help them to operate these instruments independently with minimal supervision. These services are also available for students, research scholars, and scientists from other academic institutions as well as industries on payment basis. During the year 2017, in addition to the in-house users, facility services were also used by the investigators and students from BARC, Bharathidasan University, Goa University, University of Mumbai, Bharath Serums Pvt Ltd, Premas Biotech Pvt Ltd etc.
