Overview

ROCK1 is a protein involved in cytoskeleton regulation, cell motility, and Rho kinase signaling. This protein plays a role in neurodegenerative diseases and represents a potential therapeutic target.

Structure

ROCK1 is a serine/threonine kinase with a modular structure:

• Rho-binding domain (RBD): At N-terminus, binds active RhoA
• Coiled-coil region: Mediates dimerization and localization
• Kinase domain: At C-terminus, catalyzes phosphorylation of substrates
• PH domain: Regulates activity and localization

ROCK1 exists in an autoinhibited conformation that is relieved by RhoA binding or caspase cleavage.

Normal Function

ROCK1 regulates numerous cellular processes:

• Actin cytoskeleton: Phosphorylates myosin light chain (MLC), LIM kinase
• Cell adhesion: Modulates focal adhesion dynamics
• Neuronal development: Axon guidance, dendritic spine formation
• Synaptic plasticity: Regulates AMPA receptor trafficking
• Smooth muscle contraction: Controls actomyosin contractility

In the brain, ROCK1 regulates neuronal morphology, migration, and synaptic function.

Role in Disease

ROCK1 dysregulation contributes to neurodegenerative diseases:

• Alzheimer's Disease: Enhances [tau](/proteins/tau) phosphorylation; promotes [amyloid-beta](/proteins/amyloid-beta) toxicity
• Parkinson's Disease: Facilitates [alpha-synuclein](/proteins/alpha-synuclein) phosphorylation; affects dopaminergic neuron survival
• Stroke: Increases [blood-brain barrier](/entities/blood-brain-barrier) permeability; promotes excitotoxicity
• ALS: Contributes to cytoskeletal defects and axonal transport impairment

Therapeutic Targeting

• ROCK inhibitors: Y-27632, fasudil, aspirin
• RhoA inhibitors: Targeting upstream activation
• Anti-inflammatory agents: Reducing downstream effects
