Isp7 is a novel regulator of amino acid uptake in the TOR signaling pathway

We show that the sensitivity of tsc mutant cells to rapamycin is mediated by TORC1 and can be suppressed by overexpression of the 2-oxoglutarate-Fe(II) dependent oxygenase, Isp7. We show that Isp7 is a novel regulator of amino acids uptake that acts via regulation of gene expression, both upstream and downstream of TOR signaling. suppressed by overexpression of the putative 2-oxoglutarate-Fe(II) dependent oxygenase, Isp7. We show that Isp7 is a novel master regulator of amino acids uptake that acts via regulation of gene expression, both upstream and downstream of TOR signaling.
