Two recently published studies led by Brazilian scientists reveal the key roles of multifunctional proteins, STIP1 and Maspin ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Proteins carry out many of an organism's critical functions, and they are coded for by genes. To make a protein from a gene, a cell first needs a copy of the gene in the form of a molecule called RNA.

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

Every function in a cell is associated with a particular protein or group of proteins, typically in a well-defined ...

DNA- and RNA-binding proteins (DRBPs) constitute a significant fraction of cellular proteins and have important roles in cells. Their functions include control of transcription and translation, DNA ...

Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. This RNA does not code for proteins and is copied from sections of the genome once believed to be ...

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it ...

Culminating a nearly 10 year effort, researchers have determined the atomic resolution structure of a key molecule that translates signals from a cell’s local environment into a language that the cell ...

ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds ...
