Protein: Protein VAPYRIN (MtVpy) (Protein HERMES) (D3J162)
Organism: Medicago truncatula (Barrel medic) (Medicago tribuloides)
Function: Required for arbuscular mycorrhizal (AM) symbiosis with AM fungi (e.g. Glomus versiforme and Gigaspora gigantea) both during fungal passage across root epidermis and for arbuscule formation in cortical cells; this symbiosis promotes phosphorus (P) and copper (Cu) uptake. Essential for infection by symbiotic nitrogen-fixing rhizobial bacteria (e.g. Sinorhizobium meliloti) leading to the formation of root nodules.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:19912567, ECO:0000269|PubMed:21223389}. Nucleus {ECO:0000269|PubMed:19912567, ECO:0000269|PubMed:21223389}. Cell membrane {ECO:0000269|PubMed:26234213}; Peripheral membrane protein {ECO:0000305}; Cytoplasmic side {ECO:0000305}. Note=In cells containing arbuscular mycorrhizal (AM) fungal hyphae and arbuscules, accumulates in small puncta that move through the cytoplasm, likely mobile spherical structures that are associated with the tonoplast referred to as 'tonospheres' (PubMed:19912567). Present in cytoplasmic strands below hyphopodia (PubMed:19912567). Observed associated with EX70I in zones adjacent to the periarbuscular membrane (PAM) around the arbuscule hyphal tips (PubMed:26234213). Occasionally observed in the nucleus of cells containing fungal hyphae (PubMed:19912567). {ECO:0000269|PubMed:19912567, ECO:0000269|PubMed:26234213}.
