Research and describe a cell receptor involved in cell signaling that utilizes one of the following mechanisms. 1. RTK pathway (Receptor Tyrosine Kinase Cascade) 2. GPCR (G Protein Coupled Receptor) 3. Ion Channel Receptors 4. Ligand Gated Your summary of the protein receptor must include the following: 1. Name of the receptor and its ligand. 2. A brief description of the pathway (what is activated and how). 3. Name of the pathway it is responsible for activating and what the pathway response is. (What is the cell response). 4. Is the pathway associated with the development of cancer? 5. What type of receptor is it? (Should be one of the four listed above). Solution Receptor Tyrosine Kinase (RTK) These are cell surface receptors for polypeptide growth factors, cytokines, and hormones. Binding of growth factor to the extracellular domain of an RTK leads to its dimerization.This then activates proteins cytoplasmic kinase domains.The receptor is activated by autophosphorylation of specific intracellular tyrosine residues. This inturn activates Sh2 and PTB domains. Epidermal growth factor receptor is a family of receptor tyrosine kinase. excessive erb2 signalling is associated with development of solid tumors. G Protein coupled receptor They are found in eukaryotes, yeast and animals.They are seven transmembrane domain receptors. The examples are cAMP and Phosphotidyl inositol signalling. G protein is active when the GTP is bound to it and inactive when GDP is bound. In cAMP signalling, the adenylase cyclase coverts AMP to cAMP. cAMP then activates protein kinase A Ion channel receptors are cell membrane bound receptors. They are mainly present on synaptic structures.Excitation of presynaptic neuron cause release of neurotransmitter that bind to post synaptic neurons and opens the ion channels.example - N-methyl-D-aspartate receptor (NMDA receptor), NMDA bind to NMDA receptor and activate the receptor to open cation channel..

1. Robot Tracking System
Purpose of the assignment: The project is developing robot tracking system. Its purpose is to
practice using C++ class and become familiar with OO programming in C++ Introduction: The
RobotTrack system is to keep track of Robot operation. Using this system a Robot keeps the
distance it has traveled since operation as well as the current position. The purpose of this
program is to simulate the operation of a Robot and to generate a report that summarizes the
operation of the Robot. For this assignment, there is only one Robot and initially at the location
on the first line of data file – robotTravel.txt The value in the file “robotTravel.txt”, after the first
line are the movement of the robot, S for move south 1 mile, N for move north for 1 mile.
However W is for moving west 2 miles and E is for moving 2 mile to east. After each movement,
display the current position and the distance it has traveled since leaving initial location.
Requirement: Robot class specification file : robot.h Robot class implementation file: robot.cc
Client code file: ola4.cc Robot class has public methods (interface) : void setRobot(int
xLocation, int yLocation); void displayRobot(); void moveTo( char ch); Client code may look
like: This is not exact C++ code Robot myRobot; read initial location from data file
myRobot.setRobot(x, y); read the movement from data file while ( reading data is successful)
myRobot.moveTo(movement); myRobot.displayRobot(); read the next movement; sample input
data: cp $PUB/ robotTravel.txt . 100 50 initial location S S W W S S S E E E E N N E E Sample
Output: Print the current location of the Robot, the total accumulated distance traveled since
operation after each travel (each data input). see sample output for details
