TMF1 (TATA element modulatory factor 1) is a coiled-coil golgin protein, which is localized to the entire Golgi stack. This protein has a molecular weight of 123kDa, and is composed of 1093 amino acids. The corresponding gene is localized to human chromosome 3p12-p21. It contains at least three helical turns, and multiple putative leucin zippers. It is a Ser/Thr rich protein, with its N-terminal consisting of many serine-proline and threonine-proline repeats.
Synonyms: Anti-TATA element modulatory factor antibody produced in rabbit; Anti-TMF antibody produced in rabbit
Storage: -20C
Application: Anti-TMF1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: TMF1 (TATA element modulatory factor 1) is suggested to have trans-Golgi functions. It is a putative transcription factor, which regulates the function of cellular as well as viral genes. In gel-retardation assays, it interacts with and binds to the TATA element of HIV1 (human immunodeficiency virus) and prevents its activation. Its genetic locus is subjected to frequent rearrangements in renal and lung carcinomas. During cellular stress conditions, TMF1 gets activated and changes its subcellular localization and activates multiple proteins, including Stat3, a transcription factor. Stat3 then undergoes proteasomal degradation. Its expression is suppressed in solid tumors. As it controls multiple transcription factors during cellular stress conditions, it influences angiogenesis and progression of solid tumors, such as prostate cancer.
