MW: 21.9kDa (192aa), confirmed by MALDI-TOF (Molecular weight on SDS-PAGE will appear higher). Purity >90% by SDS-PAGE. PLDN (Pallidin) 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. This protein involved in the development of lysosome-related organelles,
