Research
Areas: Cell
Signaling, Developmental Biology and Mechanobiology.
Research
Interests: To
identify novel signaling proteins and protein domains that control
cell growth and tissue/organ development in normal and disease states.
Areas of interest include cell signaling, domain-discovery, protein-protein
interaction, structural biology, developmental biology, computational
biology and mechanobiology.
Description:
Molecular recognition forms the basis for all cellular events-
from a simple bimolecular enzymatic reaction to the cascades
of multimeric protein complex in cell signaling. Fundamental
to the structure and function of a protein is its 'domain'- a
discrete, minimal modular entity that constitutes one of the
basic physical and functional unit of the polypeptide. This protein
domain can either serve as a protein docking/interaction site
or an active enzymatic unit. With the emphasis on functional
genomics, it is important to address what role does each of these
domains play and how their potential functions can be regulated
across molecular, cellular and tissue levels.
One
of the several protein domains that our group first identified
and characterized is a novel protein domain termed BCH domain
(for BNIP-2 and Cdc42GAP Homology) which play important roles
in regulating cell growth/death, differentiation, migration,
and tissue/organ development. Based on the prototypical BNIP-2
and BPGAP1 proteins, we show that distinct BCH domains could
act as key modulators for Rho and Ras small GTPases as well as
their immediate regulators such as guanine nucleotide exchange
factors (GEFs) and GTPase-activating proteins (GAPs). Current
effort is geared towards understanding how cells and tissues
respond to the dynamic forces and geometry in the environment
both under the influence of the BCH domain containing proteins
and their associated GEFs or GAPs. This will be addressed under
a newly established Research Centre of Excellence in Mechanobiology.
To compliment this and to further link cell signalling events
to developmental biology and pathophysiology, the zebrafish Danio
rerio is used as the alternate animal model.
