| Annotation description: | - KIF1A directly interacts with CaM and with the scaffolds liprin-α and TANC2. - KIF1A is regulated by a Ca2+/CaM-dependent mechanism, which allows for DCV loading. - Liprin-α and TANC2 are static PSD proteins that are not part of the KIF1A-DCV complex. - KIF1A-driven DCVs are recruited to dendritic spines by liprin-α and TANC2. "We showed that calcium, acting via CaM, enhances KIF1A binding to DCVs and increases vesicle motility. In contrast, liprin-α and TANC2 are not part of the KIF1A-cargo complex but capture DCVs at dendritic spines." |
