Cltc Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
CLTC (Clathrin Heavy Chain 1) encodes the heavy chain subunit of clathrin, a protein involved in vesicle formation and intracellular transport. Clathrin-mediated endocytosis is essential for synaptic vesicle recycling, receptor signaling, and membrane protein turnover in neurons. Dysregulation of clathrin function has been implicated in Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders.

CLTC (Clathrin Heavy Chain 1) is a gene located on chromosome 17q23.2 that encodes the heavy chain subunit of clathrin, a major protein involved in vesicle formation and intracellular trafficking[^1]. Clathrin-mediated endocytosis (CME) is essential for synaptic vesicle recycling, receptor internalization, and nutrient uptake in neurons[^2].
The clathrin triskelion consists of three clathrin heavy chains (each ~192 kDa) and three light chains, forming a distinctive three-legged structure that assembles into clathrin-coated vesicles. CLTC is ubiquitously expressed but is particularly important in neurons due to their high demand for synaptic vesicle recycling.
Dysregulation of clathrin-mediated trafficking has been implicated in several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and Huntington's disease[3][4].
CLTC encodes clathrin heavy chain 1, the structural scaffold of clathrin-coated vesicles involved in intracellular membrane trafficking. Clathrin-mediated endocytosis (CME) is the primary pathway for synaptic vesicle recycling in neurons and for receptor-mediated endocytosis in all cell types. The clathrin triskelion consists of three heavy chains (each ~180 kDa) and three light chains, forming a lattice-like structure that buds from the plasma membrane to internalize cargo molecules.
Ubiquitously expressed with high levels in brain, particularly in neurons where it is essential for synaptic vesicle recycling.
| Disease | Role | Mechanism |
|---|---|---|
| Alzheimer's Disease | Risk factor | Altered clathrin-mediated endocytosis affects APP processing and amyloid-beta clearance |
| Parkinson's Disease | Risk factor | Impaired endocytosis contributes to alpha-synuclein internalization and spread |
| Huntington's Disease | Modifier | Dysregulated endocytosis affects mutant huntingtin trafficking |
