Application Abreviews Notes
WB Use a concentration of 1 - 3 µg/ml. Can be blocked with Human Munc 13-4 peptide (ab23273). Approx. 105kDa band observed in Human T-lymphocyte and HeLa lysates (calculated MW of 123kDa according to NP_954712.1)


  • Function
    Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse. Regulates assembly of recycling and late endosomal structures, leading to the formation of an endosomal exocytic compartment that fuses with perforin-containing granules at the immunologic synapse and licences them for exocytosis. Regulates Ca(2+)-dependent secretory lysosome exocytosis in mast cells.
  • Tissue specificity
    Expressed at high levels in spleen, thymus and leukocytes. Also expressed in lung and placenta, and at very low levels in brain, heart, skeletal muscle and kidney. Expressed in cytotoxic T-lymphocytes (CTL) and mast cells.
  • Involvement in disease
    Defects in UNC13D are the cause of hemophagocytic lymphohistiocytosis familial type 3 (FHL3) [MIM:608898]; also known as HPLH3. 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 unc-13 family.
    Contains 2 C2 domains.
    Contains 1 MHD1 (MUNC13 homology domain 1) domain.
    Contains 1 MHD2 (MUNC13 homology domain 2) domain.
  • Domain
    The MHD1 and MHD2 domains mediate localization on recycling endosomes and lysosome.
  • Cellular localization
    Cytoplasm. Membrane. Late endosome. Recycling endosome. Lysosome. Colocalizes with cytotoxic granules at the plasma membrane. Localizes to endosomal exocytic vesicles.

Customer reviews and Q&As

Thank you for your enquiry. Unfortunately, in my opinion, this antibody would probably not cross-react mouse. I did an alignment of the immunogen with the mouse sequence, and got only 58% homology. The results are below: KQASQHALRPAP Immuno...

Thanks for your email. The H460 and Human Placenta lysates were the only lysates that have been tested. Please let me know if you have any additional questions.

Thank you for your enquiry. As stated on the datasheet, ab15723 is a Fast-Track antibody. Fast-Track antibodies are immunogen affinity purified and are shown by ELISA to have high titre values against their immunogen. We are currently testing them ...
