Cell Cycle
100
Cotranslational import refers to import of protein into these 2 organelles.
What are the ER and mitochondria?
100
This type of glycoprotein is used by desmosomes and in adherens junctions for cell-cell recognition and adhesion
What are cadherins? (different types for different cells)
100
This molecule walks toward the plus end of microtubules, meaning it is important for transport from the Golgi to the ER
What is kinesin?
100
This type of cell-cell adhesion prevents tracers from passing through.
What is a tight junction?
100
This is the name of the protein that has increases and decreases in expression levels that correlate with transitions through the cell cycle.
What is cyclin?
200
SNAREs are important for this cellular process.
What is exocytosis?
200
Desmosomes are associated with this component of the cytoskeleton.
What are intermediate filaments?
200
This is the name of the filament that is associated with the dark band, or A band, in muscle.
What is thick filament (myosin)?
200
Adherins junctions are associated with this component of the cytoskeleton.
What is actin?
200
These are 3 of the 4 things that are factors in determining transition into S phase
What are presence of growth factors, nutrients, acceptable cell size, and low DNA damage?
300
This experiment discussed in class demonstrated that the ER localization signal is sufficient for entry into the ER.
What is adding ER localization signal to protein not normally localized to ER?
300
As mentioned in class, bacteria invade cells by attaching to these two transmembrane adhesion proteins.
What are integrin and E-cadherin?
300
This is the purpose of radial spokes and nexin in cilia and flagella.
What is transferring microtubule sliding motion into bending motion?
300
During rearward movement in nontranslocating cells, this is the end of actin that myosin pulls toward.
What is the plus (barbed) end?
300
This is what happens to a G1 cell after fusion with a M cell in a heterokaryon.
What is M phase is activated in a non-M nucleus?
400
In the ER, this is the location of the N-terminus if there is an internal ER start sequence
What is the cytosol?
400
Name the transmembrane protein responsible for tethering the cell to the ECM
What is integrin?
400
As discussed in class, these are the two major ATP-utilizing proteins in muscles.
What are myosin and calcium-ATPases?
400
Name the protein responsible for leukocytes binding to sites of inflammation, which is then followed by integrin binding to ICAM.
What is selectin?
400
Name 2 of the 4 effects discussed in class of activation of mitotic Cdk-cyclin.
What are nuclear envelope breakdown, chromosome condensation, mitotic spindle formation, and targeted protein degradation?
500
In the plasma membrane, this is the location of the N-terminus if there is an internal ER start sequence.
What is the cytosol?
500
This is the name of the structural protein in the extracellular matrix that one would expect to find in arteries?
What is elastin? (more flexible than collagen)
500
Of ATP, ADP and Pi, ADP, or empty, this is the state of the ATP-binding site during the myosin powerstroke during muscle contraction.
What is empty?
500
These two adhesive glycoproteins in the ECM that were discussed in class are the ECM components that bind integrin.
What are fibronectin and laminin?
500
Name the two consequences discussed in class of Cdc20 activating the anaphase-promoting complex.
What are degradation of mitotic cyclin, and degradation of securin leading to breakdown of cohesin and separation of chromosomes?
