You are provided with the following information about a new receptor protein designated p15: -p15 is an integral membrane protein -the complete amino acid sequence of p15 contains 7 putative transmembrane domains -agonist-stimulation of p15 receptor-expressing cell lines results in increases in cAMP and is dependent on a heterotrimeric G protein. Describe how you would experimentally demonstrate that the G alpha s subunit is required for agonist (adrenaline) stimulated-increases in cAMP.

In female mice, both the glucocorticoid (cortisol) receptor and the estrogen receptor are expressed in liver cells (hepatocytes). The control element to which the glucocorticoid receptor binds is a short-strip of DNA that can accommodate the binding of the glucocorticoid receptor dimer. This control element is called a glucocorticoid response element (GRE). It is located1000 bp downstream from the poly-A site for the PEPCK gene. When this gene is activated by cortisol, it helps the hepatocyte to release glucose into...

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...

Please can someone help me out with the predictions.
Experiment: This “lab" will examine how disruption (mutation) of parts of a signaling pathway affect the results of activating that pathway. Specifically you will examine the effect of a factor on cell division in normal a cells ( WT- wild type) AND examine the effect of mutations that block the function of: 1. The a factor receptor (STE2 yeast) 2. The cell arrest factor (FAR1 yeast) Wild Type STE mutation FAR...
