Induction
Subcellular Location SUBCELLULAR LOCATION: Flagellar pocket {ECO:0000269|PubMed:16151248}. Note=In epimastigotes, localizes close to flagellar pocket, cytostome and to reservosomes. Reservosomes are prelysosomal-like acidic organelles found at the cell posterior end which contain the protease cruzipain and ingested proteins and lipids. In amastigotes and trypomastigotes partially co-localizes with concavalin A, a marker of the endocytic pathway. {ECO:0000269|PubMed:16151248}.
