ETS transcription factors share a conserved DNA-binding "ETS" domain and include several oncoproteins that induce tumorigenesis when overexpressed. The ETS family member E74-like factor 4 (ELF4) controls the ERK-mediated proliferation and homing of CD8+ T cells via Krüppel-like factors KLF4 and KLF2. ELF4 increase quiescence in bone marrow endothelial cells by the deregulation of cyclin-dependent kinase-4 expression and enhances regeneration of sinusoidal blood vessels.
Synonyms: Anti-E74-like factor 4 (ets domain transcription factor)
Storage: -20C
Application: Anti-ELF4 (AB1) polyclonal antibody is used to tag E74-like factor 4 proteins for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the role of E74-like factor 4 in the signaling and regulation of quiescence and proliferation of cells such at T-cells and endothelial cells.
Biochem Physiol Actions: ELF4 contains 1 ETS DNA-binding domain and belongs to the ETS family. It is transcriptional activator that binds to DNA sequences containing the consensus 5'-WGGA-3'. It transactivates promoters of the hematopoietic growth factor genes CSF2, IL3, IL8, and of the bovine lysozyme gene. It acts synergistically with RUNX1 to transactivate the IL3 promoter and also transactivates the PRF1 promoter in natural killer (NK) cells. ELF4 plays a role in the development and function of NK and NK T-cells and in innate immunity.
