TEF Antibody (PA5-106495) in ICC/IF
Immunofluorescent analysis of TEF in HeLa cells. Samples were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100, blocked with 10% serum (45 min at 25°C), incubated with mouse anti-beta tubulin and TEF polyclonal antibody (Product # PA5-106495) using a dilution of 1:200 (1 hr, 37°C), and followed by goat anti-rabbit IgG Alexa Fluor 594 (red) and goat anti-mouse IgG Alexa Fluor 488 (green).

Target Information
TEF (thyrotrophic embryonic factor), also known as KIAA1655, is a 303 amino acid nuclear transcription factor that belongs to the bZIP (basic region/leucine zipper) family and PAR (proline and acidic amino acid-rich) subfamily. TEF binds DNA as either a homodimer or heterodimer, and is known to transactivate the TSH beta promoter. While broadly expressed in adults, TEF is only found in developing embryonic anterior pituitary gland. TEF accumulates according to a robust circadian rhythm and has also been found to inhibit cell growth by downregulating beta chain expression of cytokine receptors. The functional domains of TEF are highly homologous with other members of the PAR-bZIP subfamily, including albumin D box-binding protein (DABP), human hepatic leukemia factor (HLF) and chicken vitellogenin gene-binding protein (VBP).
