CC   -!- FUNCTION: Structural protein that crystallize inside the trichocyst
CC       matrix.
CC   -!- SUBCELLULAR LOCATION: Trichocyst. Note=These are architecturally
CC       complex secretory storage granules-docked at the plasma membrane, ready
CC       to rapidly respond to an exocytotic stimulus.
CC   -!- SIMILARITY: Belongs to the TMP family. {ECO:0000305}.
CC   -!- WEB RESOURCE: Name=Protein Spotlight; Note=The arsenal of Paramecium
