A distinct mechanism regulating a pollen-specific guanine nucleotide exchange factor for the small GTPase Rop in Arabidopsis thaliana.

Proceedings of the National Academy of Sciences of the United States of America - 20 Nov 2007

Zhang Yan, McCormick Sheila

Abstract excerpt

Rop/Rac small GTPases are central to diverse developmental and cellular activities in plants, playing an especially important role in polar growth of pollen tubes. Although it is established that a class of plant-specific RopGEFs promotes the activity of Rop/Rac through the catalytic PRONE (Plant-specific Rop nucleotide exchanger) domain, not much is known about how RopGEF function is controlled to allow a...
