Detection of Human NLRP2/NALP2 by Western Blot. Western blot shows lysates of A549 human lung carcinoma cell line and LNCaP human prostate cancer cell line. PVDF membrane was probed with 1 µg/mL of Human NLRP2/NALP2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4684) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for NLRP2/NALP2 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

NALP2 (NAcht Leucine-rich repeat Protein 2, also known as NLRP2 and PAN1) is a cytosolic, 121 kDa member of the NLRP family of proteins. It is expressed in macrophages and exhibits divergent effects on inflammation. Via NF kappa B, it suppresses TNF-alpha production in response to LPS; via procaspase-1, it promotes proIL-1 beta cleavage and release. Human NALP2 is 1062 amino acids (aa) in length. It contains an N-terminal Pyrin domain (aa 9‑90), followed by a Nacht region and nine LRRs (aa 467‑1033). Four alternate isoforms exist. Three show deletions of aa’s 109‑132, 133‑154 and 847‑1062, respectively; a fourth shows a 38 aa substitution for aa’s 1‑903. No close rodent counterparts have been reported.
