Method: Electron Microscopy, Resolution 3.97Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function A0A125NTU3_HYPSL S18B1_HUMAN Proton-coupled polyamine antiporter involved in the translocation of polyamines from cytosol into secretory vesicles prior to their release via exocytosis. Uses the electrochemical proton gradient generated by a V-type proton-pumping ATPase to couple the efflux of protons with the uptake of a polyamine molecule (PubMed:25355561). Facilitates vesicular storage of spermine and spermidine in astrocytes with an impact on glutamatergic neuronal transmission and memory formation (By similarity) (PubMed:25355561). Upon antigen stimulation, regulates polyamine accumulation and release in mast cell secretory granules, which in turn potentiates mast cell degranulation and histamine secretion (By similarity).[UniProtKB:D3Z5L6]
