Guanine nucleotide exchange factors (GEFs) are
proteins or
protein domains that
activate monomeric GTPases by
stimulating the
release of
guanosine diphosphate...

deoxyribonucleic acid (DNA). Five nucleobases—adenine (A),
cytosine (C),
guanine (G),
thymine (T), and
uracil (U)—are
called primary or canonical. They...
