Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FLI1 antibody [EPR4646] (AB133485)

Immunohistochemical analysis of formalin fixed paraffin embedded human lung labelling FLI1 with ab133485 at a concentration of 0.01 µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with a OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH 8.5 for 32mins.

ab133485 Anti-FLI1 antibody [EPR4646] was incubated for 16mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

Customers are encouraged to optimise antigen retrieval conditions, antibody concentration, incubation times and temperature for best results in their own IHC assay workflow (automated and manual).

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The FLI1 protein also known as Friend leukemia virus integration 1 acts as a transcription factor. It consists of 452 amino acids resulting in a molecular mass of about 50 kDa. FLI1 is part of the ETS (E26 transformation-specific) family of transcription factors and it binds to specific DNA sequences to regulate the expression of various genes. It expresses in hematopoietic cells endothelial cells and several tissues during development. High expression levels in certain tissues suggest a significant role in diverse cellular functions.
Biological function summary

The FLI1 protein influences cell proliferation differentiation and apoptosis. It also plays a role in the regulation of genes involved in the immune response. FLI1 forms complexes with other proteins to exert its function therefore impacting gene expression in cellular contexts. Its participation in these processes indicates its regulatory impact on normal cellular development and function.

Pathways

FLI1 interacts with signaling networks that govern the hematopoietic lineage and endothelial cell function. It participates in the MAPK/ERK pathway influencing cell cycle and growth signaling. Through these pathways FLI1 has functional interactions with proteins such as GATA1 and RUNX1 establishing its importance in vascular development and hematopoiesis.

FLI1 has significant associations with Ewing sarcoma and certain leukemias. In Ewing sarcoma chromosomal translocations involve FLI1 leading to oncogenic fusion proteins that drive tumorigenesis. It also interacts with partners like EWSR1 in this context. Moreover abnormal levels of FLI1 relate to blood disorders due to its role in hematopoietic regulation. Understanding these interactions and associations aids in developing therapeutic strategies targeting these illnesses.
