The Journal of Cell Biology (JCB) is a not-for-profit publication, edited by scientists, and a leading life sciences journal. The JCB publishes papers on all aspects of cellular structure and function ...

The inner cortex of eukaryotic cells is largely composed of the protein actin, organized in a filamentous network that forms the cytoskeleton. The actin cytoskeleton plays major roles in cellular ...

Over the last several years the identification and functional characterization of the motor proteins actin and myosin in the nucleus has initiated a change in the view of nuclear processes. It is now ...

Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a ...

Biomolecular condensates are distinct molecular communities made of DNA, RNA and proteins that “condense” molecules to key locations inside cells. Intense efforts have focused on uncovering the ...

Taxol has the following effects on myogenic cultures: (a) it blocks cell replication of presumptive myoblasts and fibroblasts. (b) It induces the aggregation of microtubules into sheets or massive ...

The Fowler laboratory studies cellular architecture: how cells spatially organize themselves and their interior compartments to achieve intricate geometries, mechanical strength, and physiological ...

5. In the context of muscle contraction, what is the role of ATP (adenosine triphosphate)? a) It provides oxygen to muscles. b) It is a neurotransmitter that signals muscle contraction. c) It supplies ...
