CC   -!- FUNCTION: Actin-binding protein that interferes with host cell actin
CC       cytoskeleton. Nucleates actin polymerization and condensates actin
CC       filaments into cables (bundling). SipA potenciates SipC activity and
CC       both are required for an efficient bacterial internalization by the
CC       host cell. {ECO:0000269|PubMed:10487745}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:10972831,
CC       ECO:0000269|PubMed:7608068}. Note=Secreted via the type III secretion
CC       system 1 (SPI-1 TTSS) and inserted into the host cell plasma membrane.
CC   -!- SIMILARITY: Belongs to the invasin protein C family. {ECO:0000305}.
