Bladder cancer is a highly heterogeneous and aggressive malignancy with a poor prognosis. EGF/EGFR activation causes the detachment of SHC-binding protein 1 (SHCBP1) from SHC adapter protein 1 (SHC1), which subsequently translocates into the nucleus and ...

The Small GTP-binding Protein Rac1 Induces Cardiac Myocyte Hypertrophy through the Activation of Apoptosis Signal-regulating Kinase 1 and Nuclear Factor-κB [PDF]
The small guanine nucleotide-binding protein Rac1 has emerged as an important molecule involved in cardiac myocyte hypertrophy. Recently, we reported on apoptosis signal-regulating kinase (ASK) 1 and a transcriptional factor, nuclear factor-kappaB (NF-kappaB), as novel signaling intermediates in cardiac myocyte hypertrophy.

MIIP remodels Rac1-mediated cytoskeleton structure in suppression of endometrial cancer metastasis
Background Endometrial carcinoma (EC) is one of the most common malignancies of the female reproductive system. Migration and invasion inhibitory protein (MIIP) gene was recently discovered candidate tumor suppress gene which located at chromosome 1p36 ...

Carboxyl-terminal isoprenylation of ras-related GTP-binding proteins encoded by rac1, rac2, and ralA
Membrane localization of p21ras is dependent upon its posttranslational modification by a 15-carbon farnesyl group. The isoprenoid is linked to a cysteine located within a conserved carboxyl-terminal sequence termed the "CAAX" box (where C is cysteine, A is an aliphatic amino acid, and X is any amino acid).

SmgGDS stabilizes nucleotide-bound and -free forms of the Rac1 GTP-binding protein and stimulates GTP/GDP exchange through a substituted enzyme mechanism [PDF]
The Rac proteins, Rac1 and Rac2, are essential components of the NADPH oxidase system of phagocytes and regulate the actin assembly associated with membrane ruffling. These functions are controlled by the GTP-bound form of Rac. The biochemical interaction between Rac and its only known GDP-dissociation stimulator (termed smgGDS) was characterized ...

Phosphorylation and Activation of RhoA by ERK in Response to Epidermal Growth Factor Stimulation. [PDF]
The small GTPase RhoA has been implicated in various cellular activities, including the formation of stress fibers, cell motility, and cytokinesis. In addition to the canonical GTPase cycle, recent findings have suggested that phosphorylation further ...

The small GTP-binding proteins Rac1 and Cdc42regulate the activity of the JNK/SAPK signaling pathway
c-Jun amino-terminal kinases (JNKs) and mitogen-activated protein kinases (MAPKs) are closely related; however, they are independently regulated by a variety of environmental stimuli. Although molecules linking growth factor receptors to MAPKs have been recently identified, little is known about pathways controlling JNK activation.
