Information

The nucleus is the characteristic organelle that makes eukaryotic cells distinct from
archaea and prokaryotes. Nucleus contains genetic materials and protects itself by double layer
membrane. Like any other membrane, double layer nuclear membrane includes proteins, and
they are known as nuclear membrane proteins. In a dynamic cell, the nucleus is motile, and this
movement is mediated by the interaction between nuclear membrane proteins and cytoskeleton.
In a recent study, I have demonstrated that if this interaction between nuclear membrane proteins
and cytoskeleton is interrupted at cellular level, nucleus fails to position correctly, and the future
cell division follows the altered nuclear position. This study answers a long-standing biology
question: The nucleus decides the future cell division site. In careful observation, this event
highlights how nuclear envelope proteins regulate cell division, more precisely future division site.
Interestingly, nuclear envelope breaks down during the cell division and re-appears in the
daughter cell nucleus. What happens to the nuclear membrane proteins after the envelope breaks
down? What is the function of nuclear envelope proteins during mitosis? The research in my lab
tries to answer these fundamental questions using the Arabidopsis thaliana and Zea mays as
model systems.
