FMNL1β is phosphorylated on S1086 in a protein kinase C δ (PKCδ)-dependent manner and S1086-phosphorylated FMNL1β acts downstream of PKCδ to regulate centrosome and multivesicular bodies polarization to the immunological synapse and exosome release.
Improved technology for counting proteins captures myosin 10 dynamics throughout the filopodial lifecycle, defines requirements for initiating filopodia, and reveals a crowded filopodial tip where motors frequently exceed available actin.
