Cre recombinase tool; Slc17a7(Sodium dependent Inorganic Phosphate cotransporter) is also known as Vglut1(Glutamate transporter). When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cells expressing Slc17a7. This strain may be useful for studying glutamatergic synaptic vesicle trafficking and vesicle-bound, sodium-dependent phosphate transportation.
