Abr and Bcr are multifunctional regulators of the Rho GTP-binding protein family. [PDF]
Proceedings of the National Academy of Sciences, 1995 Philadelphia chromosome-positive leukemias result from the fusion of the BCR and ABL genes, which generates a functional chimeric molecule. The Abr protein is very similar to Bcr but lacks a structural domain which may influence its biological regulatory

Oncogene ect2 is related to regulators of small GTP-binding proteins [PDF]
Nature, 1993 We have developed an efficient expression cloning system that allows rapid isolation of complementary DNAs able to induce the transformed phenotype. We searched for molecules expressed in epithelial cells and possessing transforming potential to fibroblasts, and cloned a cDNA for the normal receptor of a growth factor secreted by NIH/3T3 cells. Here we

Small GTP-binding protein Ran is regulated by posttranslational lysine acetylation [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance The small GTPase Ran plays fundamental roles in cellular processes such as nucleo-cytoplasmic transport, mitotic spindle formation, and nuclear envelope assembly. Recently, Ran was found to be lysine acetylated, among others, in functionally important regions such as switch I and switch II.

The small GTP-binding protein Rac is a regulator of cell death in plants [PDF]
Proceedings of the National Academy of Sciences, 1999 Cell death plays important roles in the development and defense of plants as in other multicellular organisms. Rapid production of reactive oxygen species often is associated with plant defense against pathogens, but their molecular mechanisms are not known.

An essential GTP‐binding protein functions as a regulator for differentiation in Streptomyces coelicolor [PDF]
Molecular Microbiology, 1998 The Streptomyces coelicolor obg gene, which encodes a putative GTP‐binding protein of the Obg/Gtp1 family, was characterized. The obg gene was essential for viability. Introduction of multiple copies of obg into wild‐type S. coelicolor suppressed aerial mycelium formation. A single amino acid substitution at any of six positions was introduced into the

Correction: Oncogene ect2 is related to regulators of small GTP-binding proteins [PDF]
Nature, 1993 Nature 362, 462-465 (1993) THE amino-acid numbering of Ect2 and CDC24 in Fig. 2b of this letter is incorrect. The numbers for Ect2 should be 279, 330, 382, 429 and 482 (from top to bottom). Amino acids of CDC24 are numbered according to the initial publication18 and not according to the revised sequence as indicated in the figure legend.

Regulation of lymphocyte-mediated killing by GTP-binding proteins [PDF]
Journal of Leukocyte Biology, 2003 Abstract Exocytosis of granules containing apoptosis-inducing proteins is one mechanism of target cell killing by cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Granules containing perforin and granzymes are redistributed to the area of cell contact initiated by specific interactions between surface ligands on a target ...

GTP-Binding Proteins and Regulated Exocytosis [PDF]
Critical Reviews in Oral Biology & Medicine, 1999 Regulated exocytosis, which occurs in response to stimuli, is a two-step process involving the docking of secretory granules (SGs) at specific sites on the plasma membrane (PM), with subsequent fusion and release of granule contents. This process plays a crucial role in a number of tissues, including exocrine glands, chromaffin cells, platelets, and ...
