With a scholarship from the Graduate school in Immunomodulation in Germany, Arnab worked on his PhD thesis at Institute of Pathology, University of Wuerzburg.
His PhD project was focused on the regulation of transcription factor (NFATc1) function by sumoylation and its consequences in T cell differentiation. He moved to Cambridge University, UK for a postdoctoral research project involving TAO1 kinase protein controls mitosis.
At Institute of biochemistry (Goethe University Frankfurt) he investigated the mechanisms by which reverse sumoylation signaling regulates transcriptional processes. Currently, his project at the Institute of Molecular and Cell Physiology addresses the effect of natural occurring myosin mutations in human familial hypertrophic cardiomyopathies. By employing TIRFM and optical trapping, he is trying to understand the effect of sumoylation on molecular motor proteins at a single molecule resolution. His other projects address epigenetic regulations that dictate muscle function and muscle atophy.

  • Cell biology, Biochemistry and Molecular Biology
    Isolation and in vitro culture of CD34+ stem cell from human cord blood. Isolation and in vitro culture of mouse lymphocytes (CD4+ T cells, CD4+CD25+ regulatory T cells) followed by FACS. Generation of stable cell line (conditional protein expression, Flip-in tet-on and tet-off system). Gene-specific proteomics by exploiting CRISPR/Cas9 genome editing tool, 2-D gel electrophoresis, chromatin immunoprecipitation (ChIP), ChIP-Seq, coimmunoprecipitation, reporter gene activity assay, western Hybridization. Molecular cloning, DNA sequencing, and site-directed mutagenesis. Tandem affinity purification (TAP) of bait proteins followed by mass spectrometric analysis. Real time qPCR analysis of homeobox gene expression. Expression (in E. coli. and mammalian cells) and purification of recombinant protein by affinity chromatography, siRNA-mediated protein knock down.
  • Mass spectrometry (MS) and large-scale proteomics
    I extensively work with LTQ Velos and Orbitrap elite mass spectrometers (related techniques, troubleshooting associated with the MS system hardware and software) on a regular basis in the core MS facility in our institute (IBCII, Frankfurt). Maintenance and calibration of these mass spectrometers was a part of my regular job. In combination with other core members, I have generated a MS-based technology platform and offered proteomics-based solution to my collaborators. By using LC/MS-based techniques I have perform various types of proteomic analysis such as SILAC-based studies, label-free quantifications, Di-gly SUMO proteomics.
  • Microscopy
    Confocal laser scanning microscopy. Total Internal Reflection Fluorescence (TIRF) microscopy.
