Function

DYNLT3 encodes a dynein light chain protein that is part of the cytoplasmic dynein motor complex. Like DYNLT1, DYNLT3 can form homodimers and may have distinct cargo binding specificities compared to other dynein light chains. DYNLT3 is expressed in [neurons](/entities/neurons) and has been implicated in the transport of signaling molecules and organelles. While its specific neuronal functions are less characterized than DYNLT1, DYNLT3 is thought to play complementary roles in dynein-mediated transport. Studies suggest alterations in dynein function may contribute to the pathogenesis of spinal muscular atrophy and Huntington's disease.

Expression

DYNLT3 is expressed in:

• Brain (cerebral [cortex](/brain-regions/cortex), hippocampus)
• Testis
• Oviduct
• Various tissues with ciliary/flagellar function

Expressed in tissues with high transport requirements.

Disease Associations

| Disease | Role | Mechanism |
|---------|------|-----------|
| Alzheimer's Disease | Risk/Progression | Various mechanisms depending on gene function |
| Parkinson's Disease | Risk/Progression | Various mechanisms depending on gene function |
| Amyotrophic Lateral Sclerosis | Risk/Progression | Various mechanisms depending on gene function |

Therapeutic Implications

Targeting DYNLT3 has therapeutic potential in neurodegenerative diseases through:

• Gene therapy approaches for loss-of-function variants
• Small molecule modulators of protein function
• Protein supplementation strategies
