Vesicle trafficking protein that functions in the secretory pathway (Probable). Acts in coordination with SYP123 to mediate tip-focused membrane trafficking for root hair tip growth (PubMed:24642714). Functions in root hair elongation by forming SNARE complexes with VAMP721,VAMP722 or VAMP724 (PubMed:24642714). Involved in cytokinesis (PubMed:29396117). Acts as a cell plate-specific syntaxin, required for the fusion of vesicles at the plane of cell division (PubMed:29396117). Required for secretory trafficking to the plasma membrane during interphase (PubMed:29396117). Involved in the regulation of density of the H(+) ATPase proteins at the plasma membrane of root and shoot in epidermal cells (PubMed:30926657). Modulation of SYP132 expression by auxin affects clathrin-sensitive H(+) ATPase traffic from the plasma membrane, and influences apoplastic acidification and plant growth (PubMed:30926657). Part of the t-SNARE complex. A number of isoforms are produced. According to EST sequences. Widely expressed in all tissues throughout plant development. Induced by auxin in roots (PubMed:30926657). Down-regulated by auxin in shoots (PubMed:30926657). Defect in cytokinesis in embryos and defect in seedling growth. Plants silencing SYP132 exhibit reduced root hair length. Belongs to the syntaxin family.
