Death Effector Filament-forming Ced 4 like Apoptosis Protein (DEFCAP) is a novel apoptotic protein of the mammalian Ced 4 family. It has two isoforms: DEFCAP-L and DEFCAP-S. The deduced amino acid sequences of these two alternately spliced isoforms only differ by 44 amino acids at the C-terminus. DEFCAP contains a caspase recruitment domain (CARD), a domain that with the proper stimulation can recruit caspases to form cytoplasmic structures called death effector filaments, which in turn initiate the apoptotic signaling pathway.

機能Able to form cytoplasmic structures termed death effector filaments. Enhances APAF1 and cytochrome c-dependent activation of pro-caspase-9 and consecutive apoptosis. Stimulates apoptosis through activation of caspase-3. Involved in activation of caspase-1 and caspase-5 as part of the NALP1 inflammasome complex which leads to processing and release of IL1B and IL18. Binds ATP.
組織特異性Widely expressed. Isoform 1 and isoform 2 are expressed in peripheral blood leukocytes and chronic myelogenous leukemia cell line K-562, followed by thymus, spleen and heart. Also detected in brain, lung, placenta, small intestine, colon, kidney, liver, muscle, testis and epithelial cells. Absent from hematopoietic progenitor cells but expressed upon differentiation of cells into granulocytes and, to a lesser extent, monocytes. In peripheral blood cells, highest levels are found in T-lymphocytes, granulocytes and monocytes. Expression is significantly increased in bone marrow blast cells of some acute leukemia patients but not in solid tumors.
関連疾患Genetic variations in NLRP1 are associated with susceptibility to vitiligo (VTLG) [MIM:193200]. VTLG is a pigmentary disorder of the skin characterized by circumscribed depigmented macules and patches, commonly on extensor aspects of extremities, on the face or neck and in skin folds. It is a progressive disorder in which some or all of the melanocytes in the affected skin are selectively destroyed. It is a multifactorial disorder with a complex etiology probably including autoimmune mechanisms, and is associated with an elevated risk of other autoimmune diseases. Genetic variations in NLRP1 gene are associated with susceptibility to vitiligo-associated multiple autoimmune disease type 1 (VAMAS1) [MIM:606579]. VAMAS1 is an autoimmune disorder characterized by the association of vitiligo with several autoimmune and autoinflammatory diseases including autoimmune thyroid disease, rheumatoid arthritis and systemic lupus erythematosus.
IHC image of NALP1 staining in human cerebral cortex formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab3683, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
