Map1Lc3A Protein plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Map1Lc3A Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The MAP1LC3A gene (Microtubule-Associated Protein 1 Light Chain 3 Alpha) encodes a core protein of the autophagy machinery. LC3 is essential for autophagosome formation and is widely used as a marker for autophagy activity in neurodegenerative diseases.
| Attribute | Value |
|---|---|
| Protein Symbol | MAP1LC3A (LC3A) |
| Full Name | Microtubule-Associated Protein 1 Light Chain 3 Alpha |
| NCBI Protein ID | NP_115903.1 |
| UniProt ID | Q9Y9P3 |
| Molecular Weight | 14.5 kDa |

LC3A is a fundamental autophagy protein:
LC3 undergoes processing:
| Form | Modification | Function |
|---|---|---|
| Pro-LC3 | Full-length | Cytosolic |
| LC3-I | Cytosolic | Unconjugated |
| LC3-II | Phosphatidylethanolamine | Membrane-bound |
The conversion of LC3-I to LC3-II via phosphatidylethanolamine conjugation is essential for autophagy.
LC3 recognizes cargo via LIR (LC3-Interacting Region) motifs:
Key structural elements:
LC3A expression in brain cell types:
| Cell Type | Expression | Notes |
|---|---|---|
| Neurons | High | Synaptic function |
| Astrocytes | Moderate | Stress response |
| Microglia | Moderate | Immune function |
| Oligodendrocytes | Low | Myelin maintenance |
