Actin, one of the most abundant proteins in nature, participates in countless cellular functions ranging from organelle trafficking and pathogen motility to cell migration and regulation of gene ...

Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell's fusion, movement and are involved in many other ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...

This is a preview. Log in through your library . Abstract Tropomodulin is a pointed end capping protein for tropomyosin-coated actin filaments that is hypothesized to play a role in regulating the ...

Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. In the ...

“We are answering fundamental questions of life that scientists have been trying to answer for several decades”, remarks Raunser. In eukaryotic cells, actin proteins are abundant and tend to join ...
