Proteins in this group contain a C3H2C3 RING finger. E3 ubiquitin ligase is part of an enzymic cascade, the end result of which is the ubiquitination of proteins. In this cascade, E1 activates the ubiquitin, the activated ubiquitin is carried by E2, and E3 recognizes the acceptor protein as well as catalyzes the transfer of the activated ubiquitin from E2 to this acceptor. GRAIL, a transmembrane protein localized in the endosomes, controls the development of T cell clonal anergy, and may ubiquitinate membrane-associated targets for T cell activation. GRAIL1 is associated with, and regulated by, two isoforms of otubain 1 (the ubiquitin-specific protease). Additional E3s belonging to this group include human (h)Goliath and Xenopus GREUL1 (Goliath Related E3 Ubiquitin Ligase 1). hGoliath and GRAIL both have the property of self-ubiquitination. hGoliath is expressed in leukocytes; its expression and localization is not modified in leukemia.

PA_VSR: Protease-associated (PA) domain-containing plant vacuolar sorting receptor (VSR). This group includes various PA domain-containing VSRs such as garden pea BP-80, pumpkin PV72, and various Arabidopsis VSRs including AtVSR1. In contrast to most eukaryotes, which only have one or two VSRs, plants have several. This may in part be a reflection of having a more complex vacuolar system with both lytic vacuoles and storage vacuoles. The lytic vacuole is thought to be equivalent to the mammalian lysosome and the yeast vacuole. Pea BP-80 is a type 1 transmembrane protein, involved in the targeting of proteins to the lytic vacuole; it has been suggested that this protein also mediates targeting to the storage vacuole. PV72 and AtVSR1 may mediate transport of seed storage proteins to protein storage vacuoles. The significance of the PA domain to VSRs has not been ascertained.
