靶标信息
SYP121 encodes a plasma membrane-resident Qa-SNARE (syntaxin) that concentrates at the cell surface where secretory vesicles fuse and, in highly polarized contexts, is targeted to discrete plasma membrane domains (e.g., guard-cell and tip-growing cell regions). The protein is a single-pass membrane anchor with a C-terminal transmembrane helix, preceded by a cytosolic SNARE (Qa) motif that forms coiled-coil complexes with partner SNAREs, and an N-terminal regulatory region that includes an Habc-like folded domain and short N-terminal motifs important for partner binding and control of SNARE assembly. Functionally, SYP121 promotes post-Golgi exocytosis to the plasma membrane and helps define cargo delivery routes, thereby supporting growth and cell surface remodeling; it also couples membrane trafficking to transport activity by directly regulating and/or recycling key plasma membrane channels, including inward-rectifying K+ channels that drive guard-cell osmotic uptake during stomatal opening, and aquaporins that tune membrane water permeability. Beyond housekeeping secretion, SYP121 contributes to stimulus-responsive membrane fusion through regulated SNARE complex formation (including phosphorylation-dependent enhancement of pairing with R-SNARE partners) and participates in processes such as stomatal dynamics, polarized cell expansion, and defense-related cell wall fortification at attempted pathogen entry sites.
