Protein Domain
Type: Domain
Description: WDR59 is a component of GATOR2 complex, which also includes another four subunits, Seh1, Sec13, Sea2/WDR24, and Mio/Sea4. GATOR2 and GATOR1, which is composed of three subunits, DEPDC5, Nprl2, and Nprl3, form the Rag-interacting complex GATOR (GAP Activity Towards Rags). Inhibition of GATOR1 subunits makes mTORC1 signaling resistant to amino acid deprivation. In contrast, inhibition of GATOR2 subunits suppresses mTORC1 signaling and GATOR2 negatively regulates DEPDC5. WDR59 contains an N-terminal WD40 domain followed by a RWD domain, and a C-terminal RING-H2 finger with an unusual arrangement of zinc-coordinating residues. The cysteines and histidines in RING-H2 finger are arranged as a modified C3H3C2-type, rather than the canonical C3H2C3-type. Sea3 is the yeast counterpart of WDR59. It is not included in this entry [].

Description: This entry represents GATOR complex protein WDR24, a component of the GATOR subcomplex GATOR2. GATOR2 is part of the amino acid-sensing branch of the TORC1 signaling pathway, activating mTORC1 by inhibition of the GATOR1 subcomplex. The GATOR2 complex consists of MIOS, SEC13, SEH1L, WDR24 and WDR59 []. WDR24 has a secondary role in the GATOR-independent promotion of lysosome acidity and regulation of autophagic flux [].This entry also includes the restriction of telomere capping protein 1 (Rtc1 or Sea2) from the budding yeast Saccharomyces cerevisiae. It is a component of the SEA complex, termed as GATOR in mammals, which coats the vacuolar membrane and is involved in intracellular trafficking, autophagy, response to nitrogen starvation, and amino acid biogenesis [, ].
