Modified RING finger, H2 subclass (C3H3C2-type), found in WD repeat-containing protein mio and simialr proteins; This family contains Mio,its counterpart Sea4 from yeast, and other homologs. Mio/Sea4 is a component of the GATOR2 complex, which also includes another four subunits, Seh1, Sec13, Sea2/WDR24, and Sea3/WDR59. 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. Mio interacts with endogenous RagA and RagC, and plays an essential role in the activation of mTOR Complex 1 (mTORC1) by amino acids. In GATOR2, Mio and Seh1 localize to lysosomes and autolysosomes, and form a heterodimer that is required to oppose the TORC1 inhibitory activity of the Iml1/GATOR1 complex to prevent the constitutive down-regulation of TORC1 activity in later stages of oogenesis. A tissue-specific requirement is necessary for Mio to be involved in cell growth in the female germ line. Mio contains an N-terminal WD40 domain and a C-terminal RING-H2 finger with an unusual arrangement of zinc-coordinating residues. The cysteines and histidines in the RING-H2 finger are arranged as a modified C3H3C2-type, rather than the canonical C3H2C3-type.

WD40 domain, found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly; typically contains a GH dipeptide 11-24 residues from its N-terminus and the WD dipeptide at its C-terminus and is 40 residues long, hence the name WD40; between GH and WD lies a conserved core; serves as a stable propeller-like platform to which proteins can bind either stably or reversibly; forms a propeller-like structure with several blades where each blade is composed of a four-stranded anti-parallel b-sheet; instances with few detectable copies are hypothesized to form larger structures by dimerization; each WD40 sequence repeat forms the first three strands of one blade and the last strand in the next blade; the last C-terminal WD40 repeat completes the blade structure of the first WD40 repeat to create the closed ring propeller-structure; residues on the top and bottom surface of the propeller are proposed to coordinate interactions with other proteins and/or small ligands; 7 copies of the repeat are present in this alignment.
