Function
Prevents homeodomain proteins (e.g. STM) association to plasmodesmata and, consequently, cell-to-cell transport. Binds to RNA. Alters STM RNA binding capacity (PubMed:17965274). Regulates cytoskeleton (e.g. actin) organization that determinates cell shape (PubMed:8893552, PubMed:19074626). Regulates stomata patterning and drought tolerance (PubMed:19074626). Involved in restricting tobamovirus (e.g. oilseed rape mosaic virus) infectivity, probably by interfering with cell-to-cell virus movement (PubMed:19074626).
