LDS1 — Arabidopsis thaliana

Summary

AT1G43890, also known as LDS1 or RAB18, encodes a Ras-related protein RABC1, a small GTPase with GTPase activity and GTP binding. In Arabidopsis thaliana, this gene is associated with responses to abscisic acid, drought, salt, freezing, dehydration, and phosphate deficiency, as well as with abscisic acid signaling. It has been linked to traits including abscisic acid content and sensitivity, seed longevity and dormancy, transpiration rate, stomatal opening, root length, plant height, and calcium concentration. The encoded protein localizes to the stress granule, endoplasmic reticulum, plasmalemma, and nucleus. Annotated biological process associations include response to oleate, regulation of phosphatidylcholine anabolism, membrane depolarization, and S-nitrosylation.
