Detection of Human NLRP1/NALP1 by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected, transfected with human NLRP1/NALP1 or transfected with NALP3, THP-1 human acute monocytic leukemia cell line, and Ramos human Burkitt's lymphoma cell line. PVDF Membrane was probed with 0.5 µg/mL of Sheep Anti-Human NLRP1/NALP1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6788) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for NLRP1/NALP1 at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: NLRP1/NALP1

NALP1 (NAcht, Leucine-rich repeat and PYD domain containing protein 1; also NAC, CARD7, DEFCAP and CLR17.1) is a 160-170 kDa member of the NLRP family of molecules. It is expressed in dendritic cells, neutrophils, T and B cells, alveolar macrophages, permatogonia, neurons, plus intestinal columnar epithelium, and is found in both cytoplasm and nucleus. NALP1 promotes apoptosis plus IL-1 beta and IL-18 maturation by activating caspase-1 and -5. It does so by forming a 700 kDa inflammasome comprised of NALP1, ASC plus caspase-1 and -5. Bacterial wall peptidoglycan binds to NALP1, promoting ATP binding, NALP1 oligomerization, and caspase activation. Human NALP1 is 1473 amino acids (aa) in length. It contains an N-terminal DAPIN domain (aa 1-92), a NACHT domain (aa 328-637), seven consecutive LRRs (aa 704-1236) and one CARD region (aa 1374-1463). Alternate splice forms exist that range in size from 70 kDa-150 kDa. Either individually, or in combination, there can be a 19 aa substitution for either aa 1353-1473 or aa 1368-1472, a deletion of aa 91-260, 958-987 or 1262-1305, and a 43 aa insert after Leu785. Over aa 1-323, human NALP1 shares less that 20% aa identity with mouse NALP1.
