STX11 Antibody – Rabbit Polyclonal

STX11: SNARE that acts to regulate protein transport between late endosomes and the trans-Golgi network. Defects in STX11 are the cause of familial hemophagocytic lymphohistiocytosis type 4 (FHL4); 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. Belongs to the syntaxin family.
