The syntaxin family of soluble @entity8816 sensitive factor adaptor protein receptors (SNAREs) is known to play an important role in the fusion of transport vesicles with specific organelles. Twenty-four syntaxins are encoded in the genome of the model plant @entity958 . These 24 genes are found in 10 gene families and have been reclassified as syntaxins of plants (SYPs). Some of these gene families have been previously characterized, with the SYP2-type syntaxins being found in the prevacuolar compartment ( @entity2634 ) and the SYP4-type syntaxins on the @entity10747 ( @entity10747 ). Here we report on two previously uncharacterized syntaxin groups. The SYP5 group is encoded by a two-member gene family, whereas @entity69528 is a single gene. Both types of syntaxins are localized to multiple compartments of the endomembrane system, including the @entity10747 and the @entity2634 . These two groups of syntaxins form SNARE complexes with each other, and with other @entity958 SNAREs. On the @entity10747 , @entity69528 forms complexes with the SNARE VTI12 and either @entity69529 or @entity69530 . @entity69531 and @entity69528 interact with each other and with VTI12, most likely also on the @entity10747 . On the @entity2634 , a SYP5-type syntaxin interacts specifically with a SYP2-type syntaxin, as well as the SNARE VTI11, forming a SNARE complex likely involved in @entity10747 -to- @entity2634 trafficking.

Interactions between syntaxins identify at least five SNARE complexes within the Golgi/prevacuolar system of the XXXX cell.
