M. Geyer et A. Wittinghofer, GEFS, GAPS, GDIS AND EFFECTORS - TAKING A CLOSER (3D) LOOK AT THE REGULATION OF RAS-RELATED GTP-BINDING PROTEINS, Current opinion in structural biology, 7(6), 1997, pp. 786-792
Cell biology depends on the interactions of macromolecules, such as pr
otein-DNA, protein-protein or protein-nucleotide interactions. GTP-bin
ding proteins are no exception to the rule. They regulate cellular pro
cesses as diverse as protein biosynthesis and intracellular membrane t
rafficking. Recently, a large number of genes encoding GTP-binding pro
teins and the proteins that interact with these molecular switches hav
e been cloned and expressed. The 3D structures of some of these have a
lso been elucidated. (C) Current Biology Ltd ISSN 0959-440X.
