...orms, these sacs arranged themselves in an orderly fashion at the synapse, but in the LIS1-mutant worms, the researchers noticed gaps in the synaptic vesicle line-up. The LIS1 protein interacts with a molecular motor protein called dynein, which helps transport the neurotransmitter vesicles within cells.

...ith DNA in the nuclei of cells. Histones are the fashion mavens of the molecular world. They must be wearing something! Normally, they have an affinity for wrapping themselves with DNA, and so DNA wraps around them in the cell, forming a compact bundle of DNA and protein called chromatin. This allows the D...Researchers develop blood test that can detect genetic changes in progressive breast cancer

The proteins, called condensins, are important for a variety of housekeeping processes in chromosomes, but the mechanics behind their function have been largely unknown.

However, when they were given to another compartment known as a lysosome, the MHC-protein display failed to provoke the type B T cells. Scientists then tried the experiment in cells in which the gene for the H2-DM p......e bush baby, they found that it was organized in a fashion strikingly similar to that of several monkey species, including the owl monkey. As a bush baby was presented with a pattern that filled its entire visual field, neurons throughout the region responded, indicating that it maps the retinas of both eyes...New method is first to mimic subtle genetic changes

These results were confirmed in different types of cells and by increasing or decreasing expression of functionally different native mouse genes.
