A technique that identifies the 3D arrangement of a protein by creating a crytal from the protein and bombarding the crystal with x-rays.

These are a type of mutant where the protein that is mutated functions correctly at one temperature but abnormally at another temperature.

A form of endocytosis which takes up particulate molecules rather than molecules dissolved in liquid. This is " cell eating". It can be utilised by immmune cells as a specialised function.

A type of endocytosis which takes up molecules dissolved in liquid. Literally means "cell drinking"

One type of motor protein that uses the energy of ATP to move along the cytoskeleton.

uptake of material into a cell by an invaginationof the plasma membrane into the cytoplasm of the cell.There are several differeny types of endocytosis.

This is composed of actin and myosin protein filaments and is found throughout the cytoplasm of a cell. It contributes and maintains a cells morphology and allows directed transport of components of the cell including vesicles. Transport is directed by molecular motors dyenin and kinesisn.

As a protein is being synthesised on a ribosome of the rough endoplasmic reticulum it is directly imported into the golgi.

Some thing such as a molecule that is produced continually. Opposite of regulated.

This an assembly of molecules that work in conjunction with one another. They are held together by non-covalent bonds. The fusion machinery forms a protein complex.
