Figure 3.
Functional domains in known late-domain-interacting ESCRT-pathway components. The following domains are indicated: UEV, ubiquitin E2 variant; PRD, proline-rich domain; CC, coiled-coil; SB, steadiness box; Bro1, BCK1-like resistance to osmotic shock; V, V domain; C2, conserved domain 2; WW, WW domain; HECT, homologous to the E6-AP carboxyl terminus. Late domain motifs and their binding sites are shown in color (PT/SAP, red; YxxL, blue; PPxY, green). Binding sites for other ESCRT pathway components are indicated in black.
