CC -!- FUNCTION: Plays an important role in membrane trafficking through the
CC secretory apparatus. Not involved in endocytic trafficking to lysosomes
CC (PubMed:17632513). Acts in concert with CCZ1, as a guanine exchange
CC factor (GEF) for RAB7, promotes the exchange of GDP to GTP, converting
CC it from an inactive GDP-bound form into an active GTP-bound form (By
CC similarity). {ECO:0000250|UniProtKB:Q86VX9,
CC ECO:0000269|PubMed:17632513}.
CC -!- SUBUNIT: Interacts with CCZ1 (By similarity). Found in a complex with
CC RMC1, CCZ1, MON1A and MON1B (By similarity). The MON1A-CCZ1B complex
CC interacts with RIMOC1 (By similarity). The MON1A-CCZ1B complex
CC interacts with RAB7A and this interaction is enhanced in the presence
CC of RIMOC1 (By similarity). {ECO:0000250|UniProtKB:Q86VX9}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q6PDG8-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q6PDG8-2; Sequence=VSP_024913, VSP_024914;
CC -!- TISSUE SPECIFICITY: Widely expressed (at protein level).
CC {ECO:0000269|PubMed:17632513}.
CC -!- POLYMORPHISM: The variant Ser-374 is unique to C57BL strains. It may
CC confer the low iron phenotype observed in these strains.
CC {ECO:0000269|PubMed:17632513}.
CC -!- SIMILARITY: Belongs to the MON1/SAND family. {ECO:0000305}.
