  • Function
    SNARE that acts to regulate protein transport between late endosomes and the trans-Golgi network.
  • Involvement in disease
    Defects in STX11 are the cause of hemophagocytic lymphohistiocytosis familial type 4 (FHL4) [MIM:603552]; also known as HPLH4. Familial hemophagocytic lymphohistiocytosis (FHL) is a genetically heterogeneous, rare autosomal recessive disorder. It is characterized by immune dysregulation with hypercytokinemia and defective natural killer cell function. The clinical features of the disease include fever, hepatosplenomegaly, cytopenia, hypertriglyceridemia, hypofibrinogenemia, and neurological abnormalities ranging from irritability and hypotonia to seizures, cranial nerve deficits, and ataxia. Hemophagocytosis is a prominent feature of the disease, and a non-malignant infiltration of macrophages and activated T lymphocytes in lymph nodes, spleen, and other organs is also found.
  • Sequence similarities
    Belongs to the syntaxin family.
    Contains 1 t-SNARE coiled-coil homology domain.
  • Cellular localization
    Membrane. Golgi apparatus > trans-Golgi network membrane.
