Functions
GTPases play an important role in:
- Signal transduction at the intracellular domain of transmembrane receptors, including recognition of taste, smell and light.
- Protein biosynthesis (aka translation) at the ribosome.
- Control and differentiation during cell division.
- Translocation of proteins through membranes.
- Transport of vesicles within the cell. (GTPases control assembly of vesicle coats).

Famous quotes containing the word functions:
“Those things which now most engage the attention of men, as politics and the daily routine, are, it is true, vital functions of human society, but should be unconsciously performed, like the corresponding functions of the physical body.”
—Henry David Thoreau (1817–1862)
“Empirical science is apt to cloud the sight, and, by the very knowledge of functions and processes, to bereave the student of the manly contemplation of the whole.”
—Ralph Waldo Emerson (1803–1882)
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious—to get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
