Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

This phosphatase removes an inhibitory phosphotyrosine phosphate from serine protein kinase, mentioned in question 6, which activates kinase. What phosphatase is it?

This is what question 6 says....This is the serine protein kinase that when activated in a complex cyclin, controls onset of mitosis and M-phase of the cell cycle.

1. Cyclin A/B

2. Wee 1

3. TOR (Target of Rapmycin)

4. Cdk1

5. none of the these

***I believe the answer is Cdk1 for number 6, but I could be wrong

Which of the following statements is a lie?Select one: a. If damaged DNA is detected during the cell cycle, negative regulation is responsible in stopping the cell cycle. b. There are four cyclin proteins involved in the positive regulation of the cell cycle and they have fluctuating levels. c. To activate cyclin-dependent kinases (Cdks), they must bind to another kinase.
"Agent V" is the name of an anticancer (chemotherapy) drug. This drug works against cancer cells by inhibiting the formation of microtubules in sensitive cells. Consider a cell that is sensitive to agent V (in other words, agent V is effective at stopping growth of this cell). Based on this information, agent V would cause the cell to be frozen at which of the major cell cycle checkpoints (G1, G2 or M checkpoint)? Explain
Maturation promoting factor, MPF, is a cyclin-CDK complex that catalyzes the phosphorylation of other proteins to start mitosis. The activity level of MPF is dependent on the relative concentrations of the cyclin and CDK components of MPF (Figure 1). Based on Figure 1, which of the following describes the role of cyclin in the regulation of the cell cycle? a.During S phase, the cyclin level remains the same because DNA replication is occurring. b.During G2 phase, the cyclin level remains low, causing MPF activity to decrease, which leads cells to initiate mitosis. c.During G1 phase, the cyclin level decreases to signal the start of the resting phase of the cell cycle. d.During M phase, the cyclin level peaks, resulting in an increased binding frequency with CDK.
Insulin-like growth factor (IGF) is a peptide hormone (ligand) that binds and activates IGF receptor tyrosine kinase. Once the ligands bind the receptors, the cell undergoes cell division and multiply. Therefore, IGF is important for the growth of muscle and bone tissues during puberty. The way the IGF hormone works is that the hormone-bound IGF receptor tyrosine kinase increases the levels of cyclins inside of the cell and promotes the progression of the cell cycle. Describe how receptor tyrosine kinase works in a general sense and how cyclins regulate the cell cycle.
Regulation of the cell cycle is very complex and involves multiple proteins. In yeast, a complex of cdc2 and a mitotic cyclin is responsible for moving the cell past the G2/M checkpoint. The activity of the cyclin-dependent kinase cdc2 is inhibited when it is phosphorylated by the kinase, Wee-1. What would you predict would be the phenotype of a Wee-1 mutant yeast? What other genes could be altered in a Wee-1 deficient mutant strain that would make the cells act normally?
A cell inherits a mutation in a gene that results in a transcription factor, called NF-kB, constantly being in its active conformation. When active, NF-kB stimulates the expression of cyclins that promote progression of the cell cycle, regardless of other conditions. As a result of this mutation, how would this cell's phenotype be affected by this mutation? A) This cell would have a cancer phenotype B) This cell would grow larger in size, but would never divide C) This cell would likely undergo apoptosis D) This cell would not duplicate its chromosomes .
What would be the effect on the cell cycle if a cell acquired a mutation that rendered each of the following domains inactive? Explain your reasoning. The PSTAIR region of an M-phase Cdk The Wee1 Kinase The kinase that normally phosphorylates Sic 1 The Sic1 cyclin-Cdk inhibitor
When regulating the cell cycle of eukaryotic cells, a critical protein we discussed was cyclin. Cyclin is Select one: a. Always present in all stages of the cell cycle, but only active during the G1 - R transition b. Produced in response to signals for the cell to divide c. Produced only when retinoblastoma protein is inactivated d. Produced in response to the presence of cyclin-dependent kinase
A researcher studying a line of cancer cells noticed that cellular content of RhoBTB3 and Cyclin E1 increase and decrease through the cell cycle. a. He hypothesizes that RhoBTB3 signaling regulates the production of Cyclin E1 and the entry of the cell into mitosis. Based on the data below, explain why his results do not support this hypothesis. Identify what conclusions are supported by this data. b. Suppose that the researcher can engineer a cell line in which RhoBTB3 expression can be induced by the addition of a drug. Design an experiment using this cell line to test whether RhoBTB3 regulates the production of Cyclin E1. Describe what results he can expect if his hypothesis is correct.
What is the effect of having fluctuating cyclin levels throughout the cell cycle, while the levels of its corresponding cyclin dependent kinase stay relatively constant? Explain.
(a) the cell cycle is divided into different phases (referred to as M, G0, G1, S and G2); Can you account for what happens during the different parts of the cycle and out of it is checked? ( b) What is the difference between apoptosis and necrosis? ( c) What are caspases and what is their function in the cell?
Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent. Besides autophosphorylation, which of the following steps would be inhibited by Lapatinib? Signaling molecule binding, dimerization, and the downstream cellular response. Dimerization, and the downstream cellular response. The downstream cellular response. Phosphatase activity, dimerization, and the downsteam cellular response.
