---|---|---|
REN1_ARATH | function | Acts as a GTPase activator for the Rac-type GTPase by converting it to an inactive GDP-bound state. Maintains the global inactivation of ARAC11/ROP1 at the apex in pollen tubes in order to regulate the polar cell growth. |
REN1_ARATH | subcellular location | Localizes to the apical plasma membrane and accumulates in the clear zone of growing pollen tubes. |
REN1_ARATH | tissue specificity | Expressed in pollen and pollen tubes. |
