Guanine Nucleotide Exchange Factor
Guanine nucleotide exchange factors (GEFs) activate monomeric GTPases by stimulating the release of guanosine diphosphate (GDP) to allow binding of guanosine triphosphate (GTP). A variety of unrelated structural domains have been shown to exhibit guanine nucleotide exchange activity. Some GEFs can activate multiple GTPases while others are specific to a single GTPase.

Famous quotes containing the words exchange and/or factor:
“The first place he went into was the Royal Exchange .... where men of all ages and all nations were assembled, with no other view than to barter for interest. The countenances of most of the people showed they were filled with anxiety; some indeed appeared pleased, but yet it was with a mixture of fear.... [David] resolved to stay no longer in a place where riches were esteemed goodness, and deceit, low cunning, and giving up all things to the love of gain were thought wisdom.”
—Sarah Fielding (1710–1768)
“Children of the middle years do not do their learning unaffected by attendant feelings of interest, boredom, success, failure, chagrin, joy, humiliation, pleasure, distress and delight. They are whole children responding in a total way, and what they feel is a constant factor that can be constructive or destructive in any learning situation.”
—Dorothy H. Cohen (20th century)
