ID:PDC6I_HUMAN DESCRIPTION: RecName: Full=Programmed cell death 6-interacting protein; Short=PDCD6-interacting protein; AltName: Full=ALG-2-interacting protein 1; AltName: Full=Hp95; FUNCTION: Class E VPS protein involved in concentration and sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome. Binds to the phospholipid lysobisphosphatidic acid (LBPA) which is abundant in MVBs internal membranes. The MVB pathway appears to require the sequential function of ESCRT-O, -I,-II and -III complexes. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses). Appears to be an adapter for a subset of ESCRT-III proteins, such as CHMP4, to function at distinct membranes. Required for completion of cytokinesis. Involved in HIV-1 virus budding. Can replace TSG101 it its role of supporting HIV-1 release; this function implies the interaction with CHMP4B. May play a role in the regulation of both apoptosis and cell proliferation. SUBUNIT: Interacts with SH3KBP1. Interacts with PDCD6 and TSG101 in a calcium-dependent manner. Interacts with and SGSM3. Self- associates. Interacts with CHMP4A; the interaction is direct. Interacts with CHMP4B; the interaction is direct. Interacts with CHMP4C; the interaction is direct. Interacts with HIV-1 p6. Interacts with EIAV p9; the interaction has been shown in vitro. Interacts with CEP55; the interaction is direct; CEP55 binds PDCD6IP in a 2:1 stoechiometry. May interact with PDGFRB. Interacts with SH3GL1 and SH3GL2. Interacts with murine leukemia virus Gag polyprotein (via LYPX(n)L motif). Interacts with murine leukemia virus Gag polyprotein (via LYPX(n)L motif). INTERACTION: P03347:gag (xeno); NbExp=2; IntAct=EBI-310624, EBI-1220741; P69730:gag (xeno); NbExp=2; IntAct=EBI-310624, EBI-1220941; O75340:PDCD6; NbExp=5; IntAct=EBI-310624, EBI-352915; SUBCELLULAR LOCATION: Cytoplasm, cytosol. Melanosome. Cytoplasm, cytoskeleton, centrosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Colocalized with CEP55 in the midbody during cytokinesis. Colocalized with CEP55 at centrosomes of non-dividing cells. PTM: May be phosphorylated on tyrosine residues by activated PDGFRB. SIMILARITY: Contains 1 BRO1 domain. SEQUENCE CAUTION: Sequence=BAA92092.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
