To fold or to degrade? Proteins have to be folded to its native structure in order to perform its designated tasks and a failure to do so leads to deleterious effects. Chaperones as the name suggest prevents improper interactions and ensures proper functioning of the proteome...Read more
The winners of the 2019 Nobel Prize in Physiology or Medicine were announced here in Stockholm last week. William G. Kaelin Jr., Sir Peter J. Ratcliffe and Gregg L. Semenza were jointly awarded for their discoveries of how cells sense and adapt to oxygen availability...Read more
A bit more than two decades ago, the first Diablo game was released to the world. A game about a lone hero tasked with bringing down Diablo, one of the lords of Hell. This month we highlight a namesake to this hellish lord of terror, the protein DIABLO...Read more
Some proteins are expressed periodically during a specific stage of the cell cycle or as a response to various stimuli. As a result, at any given time some cells express the protein of interest and some do not. In the Cell Atlas we denote these images as single-cell variation (SCV). An example of a protein with such variations is CCNB1.
CCNB1, shown here in U-251 MG cells, is essential for cellular proliferation. The abundance of CCNB1 oscillates across the cell cycle, and peaks during G2/M phase. CCNB1 is expressed in the cytoplasm during interphase and translocate to the nucleus during G2/M transition...Read more
SUN2 (Sad1 and UNC84 domain containing 2), found in the nuclear membrane of cells, is an essential protein for many cellular processes. SUN plays a large role in the organization of multi-nucleated muscle cells, and dysregulation of SUN can cause muscular dystrophy among other diseases...Read more
