GO:0020007 apical complex

Term Information

ID GO:0020007
Name apical complex
Ontology Cellular Component
Definition A group of cytoskeletal structures and associated membrane-bounded organelles found at the anterior end of adult obligate intracellular protozoan parasites in the phylum Apicomplexa. The apical complex is involved in attachment to and penetration of the host cell, and in parasite proliferation.

ID Mapping

QuickGO maps between different identifier types by using a combination of mapping files provided by the databases, and using identifier cross-references supplied by UniProtKB.

If more than one identifier type needs to be used to map all required sequences, drag the selected databases to change the order in which identifiers are found.
