    2. Pon overexpression alters polar protein distribution is relevant because Pon is often used as a polarity marker in dividing progenitors.

    3. Polo directly phosphorylates Partner of Numb (Pon), an adaptor protein for Numb, and this phosphorylation event is important for Pon to localize Numb
      Title: Polo inhibits progenitor self-renewal and regulates Numb asymmetry by phosphorylating Pon.
    4. Numb and Pon rapidly exchange between a cytoplasmic pool and the cell cortex and that preferential recruitment from the cytoplasm is responsible for their asymmetric distribution during mitosis.
