SEC3A acts as an effector of RabE1b to regulate auxin transport in arabidopsis.

PloS one - 1 Jan 2026

Abstract excerpt

The establishment and architectural growth of terrestrial plants critically depend on polar auxin transport, a process primarily driven by the asymmetric distribution of PIN proteins within the plasma membrane. In Arabidopsis, the exocyst, an evolutionarily conserved octameric vesicle-tethering complex, orchestrates the recycling of PIN proteins, with subunits such as SEC6, SEC8, and EXO70A1 having established...
