Describe how Cdc14 triggers the exit from mitosis in the budding yeast, S. cerevisiae.

#Unit 2. Cellular Organization
  1. Cdc14 is a protein phosphatase, which at anaphase is activated by the mitotic exit network. Once activated, Cdc14 dephosphorylates APC/CCdh1 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  2. Cdc14 is a protein kinase, which at anaphase is activated by the mitotic exit network.  Once activated, Cdc14 phosphorylates APC/CCdh1 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  3. Cdc14 is a protein phosphatase, which at anaphase is activated by the mitotic exit network.  Once activated, Cdc14 dephosphorylates APC/CCdc20 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  4. Cdc14 is a protein phosphatase, which at metaphase is activated by the mitotic exit network.  Once activated, Cdc14 dephosphorylates APC/CCdh1, which promotes mitotic cyclin degradation and mitotic CDK inactivation.

A phylogenetic tree is shown for the three domains of life (Eukarya, Archaea, and Bacteria). The tree branches in two directions from the first point, labeled Common ancestor of all life. One branch leads in the direction of Eukarya and Archaea, and the other branch leads to Bacteria. The branch leading to Eukarya and Archaea divide, one branch leading to each domain. The branch leading to Eukarya divides into four branches. One leads to Euglenozoans, and the other three lead to branching points. The first leads to Forams in one direction, and another branching point in the other that leads to Diatoms and Ciliates. The second branching point leads to Red algae in one direction, and a branching point that leads to green algae and land plants in the other direction. The third branching point leads to amoebas in one direction, and a branching point that leads to fungi and animals in the other direction. Land plants, Fungi and Animals are all highlighted.

Muscarinic acetylcholine receptors are GPCRs that slow the rate of heart muscle contraction upon ligand binding/activation. Activation of this receptor leads to opening of potassium channels triggered by decreases in cAMP levels. The muscarinic acetylcholine receptor likely couples to:
