Entrez Gene Summary for CHMP1B Gene

  • CHMP1B belongs to the chromatin-modifying protein/charged multivesicular body protein (CHMP) family. These proteins are components of ESCRT-III (endosomal sorting complex required for transport III), a complex involved in degradation of surface receptor proteins and formation of endocytic multivesicular bodies (MVBs). Some CHMPs have both nuclear and cytoplasmic/vesicular distributions, and one such CHMP, CHMP1A (MIM 164010), is required for both MVB formation and regulation of cell cycle progression (Tsang et al., 2006 [PubMed 16730941]).[supplied by OMIM, Mar 2008]

GeneCards Summary for CHMP1B Gene

CHMP1B (Charged Multivesicular Body Protein 1B) is a Protein Coding gene. Diseases associated with CHMP1B include hiv-1. Among its related pathways are Akt Signaling and Endocytosis. GO annotations related to this gene include protein domain specific binding. An important paralog of this gene is CHMP1A.

UniProtKB/Swiss-Prot for CHMP1B Gene

  • Probable peripherally associated component of the endosomal sorting required for transport complex III (ESCRT-III) which is involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. The MVB pathway appears to require the sequential function of ESCRT-O, -I,-II and -III complexes. ESCRT-III proteins mostly dissociate from the invaginating membrane before the ILV is released. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and the budding of enveloped viruses (HIV-1 and other lentiviruses). ESCRT-III proteins are believed to mediate the necessary vesicle extrusion and/or membrane fission activities, possibly in conjunction with the AAA ATPase VPS4. Involved in cytokinesis. Involved in recruiting VPS4A and/or VPS4B and SPAST to the midbody of dividing cells. Involved in HIV-1 p6- and p9-dependent virus release.

    Quaternary structure:
    • Probable peripherally associated component of the endosomal sorting required for transport complex III (ESCRT-III). ESCRT-III components are thought to multimerize to form a flat lattice on the perimeter membrane of the endosome. Several assembly forms of ESCRT-III may exist that interact and act sequentally. Interacts with CHMP1A. Interacts with VTA1; the interaction probably involves the open conformation of CHMP1B. Interacts with CHMP2A. Interacts with VPS4A; the interaction is direct. Interacts with VPS4B; the interaction is direct. Interacts with SPAST (via MIT domain); the interaction is direct. Interacts with IST1. Interacts with MITD1. Interacts with STAMBP.
