Detection of Human Phospho-FADD (S194) by Western Blot. Western blot shows lysates of HT-29 human colon adenocarcinoma cell line and HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 1 µg/mL nocodazole or 4 mM hydroxyurea for 20 hours. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Phospho-FADD (S194) Monoclonal Antibody (Catalog # MAB7047) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for FADD at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Phospho-FADD (S194) in HeLa Human Cell Line. FADD phosphorylated at S194 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line stimulated with nocadazole using Mouse Anti-Human Phospho-FADD (S194) Monoclonal Antibody (Catalog # MAB7047) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Background: FADD

Human FADD (Fas-Associating protein with Death Domain), also known as MORT1, is a 25 kDa, 208 amino acid (aa) adaptor protein that mediates signaling of death domain-containing TNF receptor superfamily members and is thus a major regulator of apoptosis. FADD is also implicated in proliferation, cell cycle progression, tumor development, inflammation, innate immunity and autophagy. Phosphorylation on human FADD Ser194 (Ser191 in mouse) is found in T cells arrested at G2/M in the cell cycle; this effect is independent of death domain receptors. Human FADD shares 68% aa identity with mouse and rat FADD.
