Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (SEVE_DICDI | P10733)
molecular function
    GO:0003779    actin binding    Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.
    GO:0051015    actin filament binding    Interacting selectively and non-covalently with an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
    GO:0048306    calcium-dependent protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules), in the presence of calcium.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0051693    actin filament capping    The binding of a protein or protein complex to the end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits.
    GO:0030043    actin filament fragmentation    The severing of actin filaments into numerous short fragments, usually mediated by actin severing proteins.
    GO:0051014    actin filament severing    The process in which an actin filament is broken down into smaller filaments.
    GO:0044351    macropinocytosis    An endocytosis process that results in the uptake of liquid material by cells from their external environment by the 'ruffling' of the cell membrane to form heterogeneously sized intracellular vesicles called macropinosomes, which can be up to 5 micrometers in size.
cellular component
    GO:0015629    actin cytoskeleton    The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.
    GO:0045335    phagocytic vesicle    A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.
