I changed my protein. This is an important compound in vipoxin, which is the lethal neurotoxin found in the venomous viper species. This part of the venom is the toxic phospholipase inhibitor.
This is the interferon gamma protein. It plays a large role in the immune system because infected/stressed cells send it out as a cytokine “help me” signal. Last summer I measured the levels of this protein in mice with multiple … Continue reading
This receptor is one of the most important in muscle movement. It is found on all postganglionic neurons and on muscles at neuromuscular junctions. It is also the main receptor found in the parasympathetic nervous system. It is a very … Continue reading
These are two views of the different ends of the mechanosensitive channel that I posted last week Continue reading
Today let’s talk about the folding and unfolding of proteins. We’ll get some insight into the flexibility of proteins, and along the way let’s rate (thumbs up/ thumbs down) some recent attempts at depicting protein flexibility. GCSF folding IL-1 receptor … Continue reading
This protein is a transcription factor commonly found in eukaryotic cells. The thing that caught my attention with this structure was the three subunits that have configurations known as “zinc fingers”. I plan to use this for my final product … Continue reading
This is the molecule that I have chosen to represent for my final project. This is a ferritin molecule that is important in oxygen binding in hemoglobin. The molecule is made up of 24 identical protein subunits (pictured above).
This is a picture of the metal binding domain of the Amyloid Precursor protein. This is one part of the amyloid protein and I’m still trying to find an aggregate picture of many of these proteins bound together to show … Continue reading
To Do List: -Protect DNA from damage -Make proteins to halt DNA replication to repair the damage -Or, if damage is too severe, recommend that the cell commit suicide Such is the life of the p53 tumor suppressor I chose … Continue reading
The Aqequora Victoria jellyfish glows green using a protein called the green flourescent protien (GFP) and the photo above is a blue variant of GFP. Calcium ions in the Aqeuora bind to the protein, releasing the blue light.
Does anyone else see a pair of ballroom dancers in this one? You can almost see the love that ‘binds’ them… 🙂
This is one of the most common enzymes found in the cytochrome P450 mixed-function oxidase system, called CYP3A4. The P450 family of proteins is responsible for the metabolism of various compounds within the body such as drugs. CYP3A4 is a … Continue reading
Here it is finally, my protein, insulin. I like the view because it looks like two faces (one upside down) and shows all the different structures in insulin very well. Here is another view:
My current protein of interest: “Neurotrophins August 2005 Molecule of the Month by David S. Goodsell Previous Features Your brain is composed of 85 billion interconnected neurons. Individually, each neuron receives signals from its many neighbors, and based on these … Continue reading
I liked how this protein seemed symmetrical over the diagonal line that can be seen in the middle of the molecule. The diagonal space draws the attention to the center, just like the bright ions did in the membrane protein … Continue reading
Hey Guys, I’m having trouble uploading my molecule picture. When I try to upload it to the blog, I get a message about my image not being supported by blog security. Can anyone help me out? Thanks!
This is the ranasmurfin protein. It has an unusual name and it’s function is unknown. I chose to just render the backbone because I liked how it eliminated enough clutter to emphasize the symmetry of the protein. It’s a blue … Continue reading
This is a view of the 20S proteasome, a multienzymatic protein comples used to degrade damaged proteins. I liked this view because it is looking directly through the center of the barrel-shape of the protein.
I really like the symmetry of this protein. I also like how it kind of looks like a clock from this orientation. I’m very interested in trying to find a protein in which the function can be easily seen or … Continue reading
I chose this orientation because it shows the protein’s one distinct alpha helix, and it also captures one of the protein’s characteristics- length.
This one looks very interesting if you move it around, each end has an interesting looking barrel leading to the center. I chose this view because it reminded me of how viruses and bacteria are often represented in science video animations. (i.e. it has a box like “head” and multiple “legs” (actually alpha helix chains) that surround the lower center). Continue reading
I chose this orientation because it shows the simplicity of the prion, which is somewhat misleading to its crucial function. Continue reading
This is my artistic 3D rendition of the calcium pump (a membrane protein). I chose this orientation because I loved the way it enhances the beauty of the bottom alpha helices!
This weekend you should: Choose a protein Render its image in 3D using the tools in the protein data bank Orient the protein with as much artistic flair as you can muster, and Post the image as a jpg picture. … Continue reading
Hi all, I wanted to practice posting the image of a protein, so I looked for a protein with a name that might suggest a sense of humor. I found Tubby… a very important protein involved in the development of … Continue reading
I researched the Dengue Virus (tropical virus), which changes shapes when in acid, and Alpha – Amylase, which begins the process of starch digestions.
Hi guys! I’m having trouble finding how to view the protein rotationally (as phil did in class). Can anyone clue me in on how to do this through the molecule of the month website? Thanks and see ya in class … Continue reading
The proteins I looked at were caspases and collagen. I chose collagen because it is the most abundant protein in our body and its properties allow us to maintain structure in our bodies. I chose caspase because it plays a … Continue reading
Here’s a brief list of venues in town I think might be interested in hosting out Protein Portrait art exhibit… Art in the Valley Art Studios / Framing / Galleries 209 SW 2nd St. Corvallis Phone (541) 752-0811 Pegasus Frame … Continue reading
I chose to examine Acetylcholinesterase and Green Fluorescent Protein (GFP, and my, my, how varied are their purposes… from regulating brain function to making animals glow in new and exciting colors. I like the set up of the site very … Continue reading
Every rendering is a depiction, but not every depiction is a rendering
I read about fatty acid synthase, which makes fatty acids for the body, and the tobacco mosaic virus, which causes the death of the tobacco plant and is cylindrical.
For my molecule of the month research I looked at the catabolite activator protein and DNA ligase. I chose the catabolite activator protein because I thought it was really pretty. I liked the symmetry that it had and the variation … Continue reading
I looked at carbonic anhydrases (soluble) and multidrug resistance transporters (membrane) – very cool! We studied alot about carbonic anhydrases in bb45X series mainly because of how fast/efficient its enzymatic activity is at making carbonic acid. MDR transporters are found … Continue reading
The two proteins I looked at were insulin which basically tells organs to take glucose out of blood and store it after having a meal when sugar levels are higher in the body and Alcohol Dehydrogenase which converts a potentially … Continue reading
I took a look at fibrin, which is necessary for blood clotting. I also looked at ATP synthase. I was excited to see it looked like the simplified version in my biology book! Very neat.
As stated in the syllabus, the main question of our course is What does a protein look like? And guess what? That question has received an answer! What do you think? One technical note for the weekend: I’m still working out some of the bugs … Continue reading
I read about T-cell Receptors and Prions. We encountered both in BI 212, so I figured I’d check them out again. Pretty cool!
Our Wednesday action items were: -Everyone should come up with a good nickname. –Email me your official university email address. I’ll sign you up for the blog. You’ll receive an email invitation to join blogs.oregonstate.edu/psquared. After you sign your life … Continue reading
