The activity of retinoblastoma protein (Rb) is regulated primarily by phosphorylation at various serine/threonine residues. Specific patterns of pRb phosphorylation generate pRb conformational variants that mediate distinct protein-protein interactions. In an experimental cell system with a mutation in the Rb gene that encodes alanine rather than serine, which is phosphorylated in the wild-type Rb, you observe that the cell is unable to enter into the cell cycle. What this observation suggest and how do you design an experiment to substantiate...

will rate - thanks 1 - The retinoblastoma protein (RB or pRB) is an important checkpoint protein that blocks expression of cyclin E and cyclin A when it is not phosphorylated. What would be the consequence to the cell if the RB protein were mutated and could no longer be phosphorylated? A: The cell would continuously replicate regardless of other signals B: The cell could not progress through the cell cycle and replicate 2 - In the case of HER2...

Retinoblastoma (Rb) is the model genetic system for tumor suppressor genes. Analysis of DNA from retinoblastoma patients revealed that Rb is a recessive autosomal condition with LOH; however, analysis of pedigrees segregating for the familial form of Rb indicates that the condition is inherited as an autosomal dominant trait. Explain the apparent inconsistency and define LOH.

QUESTION 15 Which of the following is NOT TRUE about the Rb pathway: Rb is a tumor suppressor originally identified in retinoblastomas Alfred Knudson noted that retinoblastomas can occur in either an inherited or a sporadic fashion in the 1960s RB was cloned in the 1980s, after p53 was identified Only young children develop retinoblastomas RB is phosphorylated by CDKs, preventing binding to E2F 2 points QUESTION 16 Which of the following is NOT TRUE about p53: in tumors...

In familial retinoblastoma, are mutations in the normal RB1 gene always responsible for the loss of heterozygosity? In a family with retinoblastoma, would the mechanism of loss of heterozygosity in tumors in different members of the family be expected to be same or different? Cite some evidence supporting the conclusion that tumor cells are clonal. A gene for hereditary prostate cancer has been mapped to chromosomal location 1q25; it shows autosomal dominant inheritance. How would you go about identifying the...

A tumor cell with a mutation in Rb can divide in the absence of extracellular signals. A. If the Rb mutation is responsible for the increased cell division, is it likely that Rb is always active or always inactive? Explain your reasoning. B. Which of the following molecules would be likely to block division of these tumor cells? Select all that would block division in cells with this Rb mutation. a. An inhibitor of Ras GEF b. A...
