Cell signaling

June 17, 2020 | Duration: 55 mins.

GTPase enzymes, important mediators of signaling, do not operate alone. This session presents three talks on how GTPases and their accessory proteins, GTPase activating proteins and guanine nucleotide exchange factors, or GAPS and GEFs, select substrates, remodel the cytoskeleton and contribute to cell migration.

The talks in this virtual event were originally programmed to take place as an in-person Spotlight Session at the 2020 ASBMB Annual Meeting.
