The domain of SEC11 that bound the SYP121 N terminus was itself able to block secretory traffic in the wild type and syp122 but not in syp121 mutant Arabidopsis.
Title: Binding of SEC11 indicates its role in SNARE recycling after vesicle fusion and identifies two pathways for vesicular traffic to the plasma membrane.

Post-Golgi trafficking of PIP2;7 involves interactions with Qc-SNARE SYP61 and Qa-SNARE SYP121. The proper delivery of PIP2;7 to the plasma membrane depends on the activity of the two SNAREs, and that the SNAREs colocalize and physically interact.
Title: Arabidopsis SNAREs SYP61 and SYP121 coordinate the trafficking of plasma membrane aquaporin PIP2;7 to modulate the cell membrane water permeability.

ATL31 plays an important role in connecting the Carbon/Nitrogen response with basal immunity by promoting papilla formation through its association with SYP121.
Title: The carbon/nitrogen regulator ARABIDOPSIS TOXICOS EN LEVADURA31 controls papilla formation in response to powdery mildew fungi penetration by interacting with SYNTAXIN OF PLANTS121 in Arabidopsis.

Data indicate that SEC11 (At1g12360) binds directly with SYP121 (At3g11820) both in vitro and in vivo to affect secretory traffic.
Title: Arabidopsis Sec1/Munc18 protein SEC11 is a competitive and dynamic modulator of SNARE binding and SYP121-dependent vesicle traffic.

SYP121 facilitates stomatal reopening and they suggest that K channel traffic and recycling to the plasma membrane underpins the stress memory phenomenon of programmed closure in stomata.
Title: The trafficking protein SYP121 of Arabidopsis connects programmed stomatal closure and K? channel activity with vegetative growth.
