S318A | in Xenopus oocytes expressing mammalian excitatory amino acid transporter EAAT4, glutamate induces a current which is significantly enhanced by coexpression of isoform PIKfyve and glucocorticoid inducible kinase SGK1. The stimulating effect of PIKfyve is abrogated by mutation S318A in the SGK consensus sequence of PIKfyve. Coexpression of PIKfyve S318A mutant significantly blunts the stimulating effect of SGK1 on EAAT4 activity | Mus musculus |

physiological function | in Xenopus oocytes expressing mammalian excitatory amino acid transporter EAAT4, glutamate induces a current which is significantly enhanced by coexpression of isoform PIKfyve and glucocorticoid inducible kinase SGK1. This glutamate-induced current is significantly larger than the current in Xenopus oocytes expressing EAAT4 together with either kinase alone. Coexpression of the inactive SGK1 mutant K127N does not significantly alter glutamate-induced current in EAAT4-expressing Xenopus oocytes and abolishes the stimulation of glutamate-induced current by coexpression of isoform PIKfyve. The stimulating effect of PIKfyve is abrogated by mutation S318A in the SGK consensus sequence of PIKfyve. Coexpression of PIKfyve S318A mutant significantly blunts the stimulating effect of SGK1 on EAAT4 activity | Mus musculus |
