Summary: Predicted to enable small GTPase binding activity. Involved in positive regulation of substrate adhesion-dependent cell spreading. Acts upstream of or within several processes, including defense response to symbiont; germinal center formation; and granuloma formation. Predicted to be located in Weibel-Palade body; cytosol; and lysosome. Predicted to be active in exocytic vesicle. Used to study familial hemophagocytic lymphohistiocytosis 3.

Defective Zn(2+) homeostasis in mouse and human platelets with alpha- and delta-storage pool diseases.
Title: Defective Zn(2+) homeostasis in mouse and human platelets with α- and δ-storage pool diseases.
we found that platelet-specific Munc13-4 KO mice had a reduction in airway hyper-responsiveness and eosinophilic inflammation. Taken together, our results indicate that Munc13-4-dependent platelet dense granule release plays essential roles in hemostasis, thrombosis and allergic inflammation.
Title: Platelet Munc13-4 regulates hemostasis, thrombosis and airway inflammation.
these results demonstrate that both C2 domains of Munc13-4 play critical roles in Ca(2+)-dependent exocytosis and cytotoxicity by regulating single-granule membrane fusion dynamics in immune cells
Title: C2 Domains of Munc13-4 Are Crucial for Ca(2+)-Dependent Degranulation and Cytotoxicity in NK Cells.
In a model of systemic anaphylaxis, we found no difference between WT and Munc13-2 KO mice, but global and mast cells-specific Munc13-4 KO mice developed less hypothermia. We conclude that although Munc13-2 plays a minor role, Munc13-4 is essential for regulated exocytosis in mast cells
Title: Munc13 proteins control regulated exocytosis in mast cells.
Munc13-4 is a syntaxin 7 binding protein and an important regulator of late endosome maturation.
Title: Munc13-4 interacts with syntaxin 7 and regulates late endosomal maturation, endosomal signaling, and TLR9-initiated cellular responses.
Munc13-4 conveys Ca(2+) sensitivity to platelet SNARE-mediated membrane fusion and reveal a potential mechanism by which Munc13-4 bridges and stabilizes apposing membranes destined for fusion.
Title: Role of Munc13-4 as a Ca2+-dependent tether during platelet secretion.
Data (including data from studies in knockout mice) suggest Munc13-4 binds to Rab11 and regulates trafficking of Rab11-containing vesicles; Munc13-4 appears to regulate final steps of Rab11-positive vesicle docking at plasma membrane in exocytosis.
Title: Munc13-4 Is a Rab11-binding Protein That Regulates Rab11-positive Vesicle Trafficking and Docking at the Plasma Membrane.
Letter: data argue for a critical role of Munc13-4 and therefore also dense granule secretion in infarct progression but not in safeguarding the brain vasculature in acute ischemia.
Title: Munc13-4-mediated secretion is essential for infarct progression but not intracranial hemostasis in acute stroke.
Munc13-4 isoform is functionaly redundant in cytotoxic T lymphocytes.
Title: Different Munc13 isoforms function as priming factors in lytic granule release from murine cytotoxic T lymphocytes.
Data suggest that Rab27a and Rab27b regulate distinct steps in the bone marrow-derived mast cells (BMMC) degranulation pathway, with Rab27a/Mlph/MyoVa regulating cortical actin stability upstream of Rab27a/b/Munc13-4-dependent granule exocytosis.
Title: Distinct and opposing roles for Rab27a/Mlph/MyoVa and Rab27b/Munc13-4 in mast cell secretion.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
