Pallidin is a protein that in humans is encoded by the PLDN gene.

Function

The protein encoded by this gene may play a role in intracellular vesicle trafficking. It interacts with Syntaxin 13 which mediates intracellular membrane fusion. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.

Interactions

PLDN has been shown to interact with:

• BLOC1S1,
• BLOC1S2,
• CNO,
• Dysbindin,
• MUTED,
• SNAPAP, and
• STX12.
