ACTIN-RELATED PROTEIN 2/3 COMPLEX -
The Actin-related protein 2/3 complex is involved in the organization of the actin cytoskeleton, in particular, the nucleation of branched actin filaments. (Adapted from FBrf0144947).
Protein Function (UniProtKB)
Functions as actin-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks. Seems to contact the mother actin filament (By similarity).

    Additional comments
    FlyBase Curator comment: 'Arc-p34' renamed to 'Arpc2' to rationalize the nomenclature of genes encoding subunits of the Actin-related protein 2/3 complex, following the nomenclature suggested in FBrf0144947 which is consistent with that used in mammals.
    Source for merge of Arc-p34 anon-WO0118547.154 was sequence comparison ( date:051113 ).
    Other Comments
    S2 cells treated with dsRNA directed against Arc-p34 produce prominent filopodia and fail to internalize bound bacteria in a phagocytosis assay.
    dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
    RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in S2R+ cells: cells become retracted (unspread but flat). Kc167 cells are unaffected.
    The Arc-p34 protein part of the Arp2/3 complex.
    The Arp2/3 complex (including Arc-p34) is required for actin cap expansion and pseudocleavage furrow formation during syncytial blastoderm divisions.
