Join us for the Soft Matter Seminar on Friday, June 10 at 11:00 a.m. EST.
We will welcome speaker Debashish Chowdhury from the Department of Physics at the Indian Institute of Technology in Kanpur for his topic entitled Length control of long cell protrusions: rulers, timers and transport.
A living cell uses long tubular appendages for locomotion and sensory purposes. Hence, assembling and maintaining a protrusion of correct length is crucial for its survival and overall performance. Usually the protrusions lack the machinery for the synthesis of building blocks and imports them from the cell body. What are the unique features of the transport logistics which facilitate the exchange of these building blocks between the cell body and the protrusion? What kind of ‘rulers’ and ‘timers’ does the cell use for constructing its appendages of correct length on time? How do the multiple appendages coordinate and communicate among themselves during different stages of their existence? How frequently do the fluctuations drive the length of these dynamic protrusions out of the acceptable bounds? These questions will be addressed from a broad perspective in this talk .
