This family of conserved eukaryotic proteins are subunits of the endosome associated complex ESCRT-II which recruits transport machinery for protein sorting at the multivesicular body (MVB). This protein complex transiently associates with the endosomal membrane and thereby initiates the formation of ESCRT-III, a membrane-associated protein complex that functions immediately downstream of ESCRT-II during sorting of MVB cargo. ESCRT-II in turn functions downstream of ESCRT-I, a protein complex that binds to ubiquitinated endosomal cargo. Length = 139

ESCRT (ESCRT-I, -II, -III) complexes orchestrate efficient sorting of ubiquitinated transmembrane receptors to lysosomes via multivesicular bodies (MVBs) []. ESCRT-II recruits the transport machinery for protein sorting at MVB []. In addition, the human ESCRT-II has been shown to form a complex with RNA polymerase II elongation factor ELL in order to exert transcriptional control activity. ESCRT-II transiently associates with the endosomal membrane and thereby initiates the formation of ESCRT-III, a membrane-associated protein complex that functions immediately downstream of ESCRT-II during sorting of MVB cargo. ESCRT-II in turn functions downstream of ESCRT-I, a protein complex that binds to ubiquitinated endosomal cargo []. ESCRT-II is a trilobal complex composed of two copies of vps25, one copy of vps22 and the C-terminal region of vps36. The crystal structure of vps25 revealed two winged-helix domains, the N-terminal domain of vps25 interacting with vps22 and vps35 [].; PDB: 1W7P_B 1U5T_D 1XB4_D 3HTU_E 3CUQ_C 2ZME_D.

The HTH GntR family has many members distributed among diverse bacterial groups that regulate various biological processes. It was named GntR after the Bacillus subtilis repressor of the gluconate operon []. Family members include GntR, HutC, KorA, NtaR, FadR, ExuR, FarR, DgoR and PhnF. The crystal structure of the FadR protein has been determined []. In general, these proteins contain a DNA-binding HTH domain at the N terminus, and an effector-binding or oligomerisation domain at the C terminus (IPR011711 from INTERPRO). The DNA-binding domain is well conserved in structure for the whole of the GntR family, consisting of a 3-helical bundle core with a small beta-sheet (wing); the GntR winged helix structure is similar to that found in several other transcriptional regulator families. The regions outside the DNA-binding domain are more variable and are consequently used to define GntR subfamilies []. This entry represents the N-terminal DNA-binding domain of the GntR family.; GO: 0003700 sequence-specific DNA binding transcription factor activity, 0006355 regulation of transcription, DNA-dependent, 0005622 intracellular; PDB: 1HW1_B 1H9T_A 1HW2_A 1H9G_A 1E2X_A 3IHU_A 3C7J_A 2RA5_A 3BY6_C 3IC7_A ....
