Gene Snapshot
shrub (shrb) encodes Shrub encodes Vps32/Snf7, a filament-forming subunit of the ESCRT-III complex involved in inward membrane budding. It regulates multiple cellular processes involving ESCRTs activity including multivesicular body biogenesis, cytokinesis, membrane repair and regulation of membrane associated signaling.

ESCRT-III COMPLEX -
The ESCRT (Endosomal Sorting Complexes Required for Transport) machinery is made up of five complexes, ESCRT-0 to -III and the Vps4-Vta1 ATPase complex, which are sequentially recruited to the cytosolic face of the membrane, and mediate cargo recognition, membrane budding and fission. ESCRT-III is a dynamic complex, that assembles on endosomes. The components of the complex are less well defined, but it has four core subunits. It assembles into a filament around the neck of the budding vesicle. ESCRT-III mediates the recruitment of deubiquitinases and, together with the Vps4-Vta1 complex, which it recruits, mediates membrane scission. (Adapted from PMID:22361144 and FBrf0209668).

    Additional comments
    A 31 nucleotide deletion in the coding region of shrb4 confirms that shrb is Vps32.
    Source for merge of CG8055 anon-WO0118547.180 was sequence comparison ( date:051113 ).
    Other Comments
    shrb is required cell autonomously for dendrite pruning in sensory neurons.
    Mutants show aberrant endosome morphology, fail to degrade ubiquitinated cargoes, and a degree of endosomal accumulation of the signaling receptors.
    dsRNA made from templates generated with primers directed against Vps32 that is transfected into S2 treated with Listeria monocytogenes reveals Vps32 to be involved in Listeria monocytogenes entry, intracellular growth, and vacuolar escape.
    RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
    Area matching Drosophila EST AA264253. This EST has sequence similarity to SNF7 genes.
    shrb has a function in dendritic development.
