DCTN1 PROTEIN is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of DCTN1 PROTEIN is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
DCTN1 (p150 Glued) is the largest dynactin subunit:
- N-terminal CAP-Gly domain: Binds microtubule ends
- Coiled-coil regions: Dimerization and binding
- p150 domain: Core dynactin structure
- Dynein binding site: Activates dynein
- Dynein activator: Enhances dynein motor function
- Cargo binding: Binds various retrograde cargo
- Microtubule anchoring: Binds plus ends
- Organelle transport: Endosomes, lysosomes, aggregates
- Axonal maintenance: Essential for axonal health
- Mutations cause ALS with Perry syndrome
- Impaired retrograde transport
- Aggregate accumulation
- Links to alpha-synuclein pathology
- Retrograde transport defects
- Atypical parkinsonism
- Rapid progression
