GATOR complex protein WDR24 (WDR24)

As a part of the GATOR subcomplex GATOR2, functions within the amino acid-sensing branch of this TORC1 signaling pathway (PubMed:23723238, PubMed:27166823). Indirectly activates mTORC1 and the TORC1 signaling pathway through the inhibition of the GATOR1 subcomplex (PubMed:23723238).

It's negatively regulated by the upstream amino acid detectors SESN2 and CASTOR1 (PubMed:26449471, PubMed:26586190, PubMed:27487210). In addition to its role in regulation of this TORC1 complicated, promotes the acidification of lysosomes and eases autophagic flux (PubMed:27166823).
