\b[The N-terminal 1–29 fragment and the 1–15 fragment inhibit invadopodium formation.] Their values are around one fifth of the control, and gelatin degradation is strongly reduced too. Full-length <t-SNARE>, empty vector and the 15–29 fragment remain near control values. The images agree: the inhibitory fragments leave much more intact gelatin beneath the cells. The corresponding published <syntaxin-4> study links this phenotype to impaired cargo trafficking.<Syntaxin4-Munc18c Interaction Promotes Breast Tumor Invasion and Metastasis by Regulating MT1-MMP Trafficking by Megan I.
