In cell biology, microtubule nucleation is the event that initiates de novo formation of microtubules (MTs). These filaments of the cytoskeleton typically form through polymerization of α- and β-tubulin dimers, the basic building blocks of the microtubule, which initially interact to nucleate a seed from which the filament elongates.
The vault or vault cytoplasmic ribonucleoprotein is a eukaryotic organelle whose function is not yet fully understood. Discovered and isolated by Nancy Kedersha and Leonard Rome in 1986, [2] vaults are cytoplasmic organelles which, when negative-stained and viewed under an electron microscope, resemble the arches of a cathedral's vaulted ceiling, with 39-fold (or D 39d) symmetry.

The word liposome derives from two Greek words: lipo ("fat") and soma ("body"); it is so named because its composition is primarily of phospholipid.. Liposomes were first described by British hematologist Alec Douglas Bangham [10] [11] [12] in 1961 at the Babraham Institute, in Cambridge—findings that were published 1964.
Cell is a peer-reviewed scientific journal publishing research papers across a broad range of disciplines within the life sciences. [1] Areas covered include molecular biology, cell biology, systems biology, stem cells, developmental biology, genetics and genomics, proteomics, cancer research, immunology, neuroscience, structural biology, microbiology, virology, physiology, biophysics, and ...
The interior of cells is a crowded environment. For example, an Escherichia coli cell is only about 2 micrometres (μm) long and 0.5 μm in diameter, with a cell volume of 0.6 - 0.7 μm 3. [6] However, E. coli can contain up to 4,288 different types of proteins, [7] and about 1,000 of these types are produced at a high enough level to be easily ...
Mattison is owned in just 57% of Yahoo fantasy football leagues and 59% of ESPN leagues, making him a potential add on a bye-filled Week 12. But it'd be best to avoid the Raiders' lead back this week.
Cell adhesion molecules (CAMs) are a subset of cell surface proteins [1] that are involved in the binding of cells with other cells or with the extracellular matrix ...
