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.
An encompassing resource of differentially phosphorylated proteins forms the basis for identifying missing links in cell fate determination and morphogenesis, including, for example, microtubules as mediators of different functions in cells along the dorso-ventral axis.
Centrosomes in mammalian cells are required for timely completion of mitosis and in their absence the spindle assembly checkpoint is required to delay mitosis and allow assembly of a functional spindle.

Limiting cytoplasmic streaming contributes to maintaining spatial separation of the sperm contents from the female meiotic spindle after fertilization.
