Signaling from Rho to the actin cytoskeleton through protein kinases ROCK and LIM-kinase

M Maekawa, T Ishizaki, S Boku, N Watanabe, A Fujita… - Science, 1999 - science.org
The actin cytoskeleton undergoes extensive remodeling during cell morphogenesis and
motility. The small guanosine triphosphatase Rho regulates such remodeling, but the …

230% room-temperature magnetoresistance in CoFeB∕ MgO∕ CoFeB magnetic tunnel junctions

…, H Maehara, S Yamagata, N Watanabe… - Applied physics …, 2005 - pubs.aip.org
Magnetoresistance (MR) ratio up to 230% at room temperature (294% at 20 K) has been
observed in spin-valve-type magnetic tunnel junctions (MTJs) using MgO tunnel barrier layer …

Bias-driven high-power microwave emission from MgO-based tunnel magnetoresistance devices

…, K Tsunekawa, DD Djayaprawira, N Watanabe - Nature Physics, 2008 - nature.com
Spin-momentum transfer between a spin-polarized current and a ferromagnetic layer can
induce steady-state magnetization precession, and has recently been proposed as a working …

[HTML][HTML] p140mDia, a mammalian homolog of Drosophila diaphanous, is a target protein for Rho small GTPase and is a ligand for profilin

N Watanabe, P Madaule, T Reid, T Ishizaki… - The EMBO …, 1997 - embopress.org
Rho small GTPase regulates cell morphology, adhesion and cytokinesis through the actin
cytoskeleton. We have identified a protein, p140mDia, as a downstream effector of Rho. It is a …

Cooperation between mDia1 and ROCK in Rho-induced actin reorganization

N Watanabe, T Kato, A Fujita, T Ishizaki… - Nature cell …, 1999 - nature.com
The small GTPase Rho induces the formation of actin stress fibres and mediates the formation
of diverse actin structures. However, it remains unclear how Rho regulates its effectors to …

The small GTP‐binding protein Rho binds to and activates a 160 kDa Ser/Thr protein kinase homologous to myotonic dystrophy kinase.

…, K Okawa, A Iwamatsu, A Fujita, N Watanabe… - The EMBO …, 1996 - embopress.org
The small GTP‐binding protein Rho functions as a molecular switch in the formation of focal
adhesions and stress fibers, cytokinesis and transcriptional activation. The biochemical …

[HTML][HTML] Quantitative measurement of voltage dependence of spin-transfer torque in MgO-based magnetic tunnel junctions

…, K Tsunekawa, DD Djayaprawira, N Watanabe… - Nature Physics, 2008 - nature.com
When an electric current passes from one ferromagnetic layer via a non-magnetic layer into
another ferromagnetic layer, the spin polarization and subsequent rotation of this current can …

Single-molecule speckle analysis of actin filament turnover in lamellipodia

N Watanabe, TJ Mitchison - Science, 2002 - science.org
Lamellipodia are thin, veil-like extensions at the edge of cells that contain a dynamic array
of actin filaments. We describe an approach for analyzing spatial regulation of actin …

[HTML][HTML] p160ROCK, a Rho-associated coiled-coil forming protein kinase, works downstream of Rho and induces focal adhesions

…, M Naito, K Fujisawa, M Maekawa, N Watanabe… - FEBS letters, 1997 - Elsevier
p160 ROCK is a serine/threonine protein kinase that binds selectively to GTP-Rho and is
activated by this binding. To identify its function, we transfected HeLa cells with wild type and …

Molecular dissection of the Rho-associated protein kinase (p160ROCK)-regulated neurite remodeling in neuroblastoma N1E-115 cells

M Hirose, T Ishizaki, N Watanabe, M Uehata… - The Journal of cell …, 1998 - rupress.org
A critical role for the small GTPase Rho and one of its targets, p160ROCK (a Rho-associated
coiled coil-forming protein kinase), in neurite remodeling was examined in neuroblastoma …
