Basic information   
Locus name AT1G26670
AliasVTI12/SYP41/SYP61/VTI1B
OrganismArabidopsis thaliana
Taxonomic identifier[NCBI]
Function categoryNutrient recycling
Effect for Senescencedelay
Gene Descriptionmember of VTI1 Gene Family. Normally localizes to the transgolgi network and plasma membrane. A dominant mutation (zip1) alters the subcellular localization of VTI12 and suppresses loss of function mutation (zag1) of VTI11. Interacts with members of the SYP family. Involved in protein trafficking to protein storage vacuoles.under nutrient-poor conditions, vti12 showed an accelerated senescence phenotype
EvidenceGenetic evidence:Mutant [Ref 1, Ref 2, Ref 3, Ref 4, Ref 5, Ref 6]; Genomic evidence:microarray data [Ref 7]
