Involved in cell morphogenesis (PubMed:19392685). May have a function in membrane fusion or membrane composition (PubMed:19392685). Required for salt stress tolerance (PubMed:26133670). Regulates the salt stress-dependent post-transcriptional stabilization, cytoplasmic agglomeration, and localization to P-bodies of a subset of salt stress-regulated mRNAs (PubMed:26133670). Interacts with DCP1. Recruited to P-bodies by DCP1 in a salt stress-dependent manner. Expressed in flowers, leaves, stems, hypocotyls and roots. Distorted trichomes, decreased lobing of epidermal pavement cells, disconnected epidermal cells on various organs and shorter root hairs (PubMed:19392685). Fragmented vacuoles in root hairs (PubMed:19392685). Salt hypersensitivity.
