    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. a new and widely applicable tool to generate conditionally phosphorylated proteins to identify those whose dephosphorylation is required for cytokinesis. This approach identifies Aip1, Ede1 and Inn1 as cytokinetic regulators.

    2. Dephosphorylation of Inn1 is important for its function in promoting cytokinesis.
      Title: Cdc14-dependent dephosphorylation of Inn1 contributes to Inn1-Cyk3 complex formation.
    3. Cyk3 is part of an actomyosin ring independent cytokinesis pathway, which acts as a rescue mechanism to recruit Inn1 to the bud neck.
      Title: Cyk3 acts in actomyosin ring independent cytokinesis by recruiting Inn1 to the yeast bud neck.
    4. Data show that the Inn1 C-terminal region is necessary for localization, and distinct PXXP motifs in this region mediate functionally important interactions with SH3 domains in the cytokinesis proteins Hof1 and Cyk3.
      Title: Role of Inn1 and its interactions with Hof1 and Cyk3 in promoting cleavage furrow and septum formation in S. cerevisiae.
    5. Data indicate that recruitment of the C2 domain of Inn1 to the contractile actomyosin ring is crucial for ingression of the plasma membrane during cytokinesis in budding yeast.
