  • FunctionPossible role in modulating immune responses. Induces morphological changes including production of filopodia and microspikes when overexpressed in a variety of cell types and may be involved in dendritic cell maturation. Isoform 1 and isoform 2 have an inhibitory effect on lymphocyte proliferation.
  • Tissue specificityExpressed in lung, tonsil, thymus, placenta, kidney, fetal spleen, fetal liver and brain.
  • Sequence similaritiesBelongs to the LST1 family.
  • Cellular localizationMembrane. Golgi apparatus membrane. Endomembrane system. Also detected in a perinuclear region corresponding to the localization of the Golgi apparatus and throughout the cytoplasm.
