RT "Activation of the Rab7 GTPase by the MON1-CCZ1 complex is essential for
RT PVC-to-vacuole trafficking and plant growth in Arabidopsis.";
RL Plant Cell 26:2080-2097(2014).
CC -!- FUNCTION: Plays an important role in membrane trafficking through the
CC secretory apparatus. In complex with CCZ1, acts as a guanine exchange
CC factor (GEF) for RABG3F of the Rab7 protein family. Promotes the
CC exchange of GDP to GTP, converting RABG3F from an inactive GDP-bound
CC form into an active GTP-bound form. The RABG3F active form is involved
CC in protein trafficking from prevacuolar compartments (PVCs) to
CC vacuoles. May serve as a linker between Rab5 and Rab7 protein families
CC in PVCs and mediate PVC maturation. {ECO:0000269|PubMed:24824487}.
CC -!- SUBUNIT: Interacts with CCZ1A, CCZ1B and RABF2B.
CC {ECO:0000269|PubMed:24824487}.
CC -!- SUBCELLULAR LOCATION: Endosome {ECO:0000269|PubMed:24824487}.
CC Prevacuolar compartment {ECO:0000269|PubMed:24824487}.
CC -!- TISSUE SPECIFICITY: Widely expressed at stable levels.
CC {ECO:0000269|PubMed:16166256}.
CC -!- DISRUPTION PHENOTYPE: Severe plant growth defects, such as short root
CC phenotype, retarded growth and dwarf phenotype.
CC {ECO:0000269|PubMed:10617197}.
CC -!- MISCELLANEOUS: Due to the stability of its transcription during plant
CC development, this gene is proposed as a reference gene for transcript
CC normalization. {ECO:0000305|PubMed:16166256}.
CC -!- SIMILARITY: Belongs to the MON1/SAND family. {ECO:0000305}.
