TgMIC1 is released as part of a complex by Toxoplasma gondii prior to invasion. The complex which consists of TgMIC4-MIC1-MIC6 participates in host cell attachment and penetration and is critical in invasion. This is the C terminal domain of TgMIC1 which has a Galectin-like fold which interacts with and stabilises TgMIC6 providing a mechanism for an exit from the early secretory compartments and trafficking of the complex to micronemes [1].
