A) Draw and describe the Wnt signal transduction pathway i) with and ii) without ligand binding. ...
Last guy got it wrong - Thank you. 2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....
32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...
Developmental biology help! 1) In creating a keller explant, we are attempting to observe a the effects that bottle cells are required to achieve b autonomous convergence and extension c all of these answers d non-autonomous movements of gastrulation 2) In papers regarding frogs, quite a few genes were named will an X. What does this represent? a That the gene's products (mRNA or protein) were non-functional b none of these answers c that the gene was knocked out via...
