Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E.coli-derived human HEF1 recombinant protein (Position: K273-E421). Human HEF1 shares 83% amino acid (aa) sequence identity with mouse HEF1. (reported region: K273-E421).
• Molecular weight context: reported MW: 93-105 kDa; calculated MW: 92861 MW
• Reactivity: Human,Monkey,Mouse,Rat
• Applications: Flow Cytometry, IF, IHC, ICC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

Enhancer of filamentation 1; Enhancer of filamentation 1. Enhancer of filamentation 1 (EF1), also known as NEDD-9, is a protein that in humans is encoded by the NEDD9 gene. The protein encoded by this gene is a member of the CRK-associated substrates family. Members of this family are adhesion docking molecules that mediate protein-protein interactions for signal transduction pathways. It is mapped to 6p24.2. This protein is a focal adhesion protein that acts as a scaffold to regulate signaling complexes important in cell attachment, migration and invasion as well as apoptosis and the cell cycle. This protein has also been reported to have a role in cancer metastasis. NEDD9 is also a highly relevant cancer gene that governs metastatic potential in human melanoma. What’s more, it has been speculated that NEDD9 may be an important linking element between extracellular signaling and regulation of the cytoskeleton. Functional note: Docking protein which plays a central coordinating role for tyrosine-kinase-based signaling related to cell adhesion. May function in transmitting growth control signals between focal adhesions at the cell periphery and the mitotic spindle in response to adhesion or growth factor signals initiating cell proliferation. May play an important role in integrin beta-1 or B cell antigen receptor (BCR) mediated signaling in B- and T-cells. Integrin beta-1 stimulation leads to recruitment of various proteins including CRK, NCK and SHPTP2 to the tyrosine phosphorylated form. Reported localization: Cytoplasm, cell cortex. Nucleus. Golgi apparatus. Cell projection, lamellipodium. Cytoplasm. Cell junction, focal adhesion. Localizes to both the cell nucleus and the cell periphery and is differently localized in fibroblasts and epithelial cells. In fibroblasts is predominantly nuclear and in some cells is present in the Golgi apparatus. In epithelial cells localized predominantly in the cell periphery with particular concentration in lamellipodia but is also found in the nucleus. Isoforms p105 and p115 are predominantly cytoplasmic and associate with focal adhesions while p55 associates with mitotic spindle. Expression/tissue context: Widely expressed. Higher levels detected in kidney, lung, and placenta. Also detected in T-cells, B-cells and diverse cell lines. The protein has been detected in lymphocytes, in diverse cell lines, and in lung tissues.

Common research applications

• Western blotting: compare relative NEDD9 (Enhancer of filamentation 1) levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of NEDD9 (Enhancer of filamentation 1) across tissue regions and cell types using matched controls.
• IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.

Notes for experimental interpretation
