Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name TAF II135 (TAF4 Antibody Abstract)
Background Tightly associated factors (TAFs) play an essential role in transcriptional activation through their interaction with a variety of activators. TAF[II]135 (a.k.a. TAF[II]130) is a human homologue of Drosophila TAF[II]110, the first TAF shown to have coactivator activity. TAF[II]135 contains multiple glutamine-rich regions, as well as a coactivator domain (CAD). The glutamine-rich regions of TAF[II]135 facilitate interaction with Sp1 and CREB, which leads to enhancement of both Sp1- and CREB-mediated transcription. In addition, TAF[II]135 can potentiate transcriptional stimulation by AF-2 of the retinoic acid, thyroid hormone, and vitamine D3 receptors. However, TAF[II]135 does not interact with the AF-2s of the estrogen and retinoid X receptors. Interestingly, TAF[II]135 enhancement of CREB transcriptional activity may be disrupted by expanded polyglutamine (CAG) repeats found in at least eight different neurodegenerative disorders. Thus, TAF[II]135 may have important coactivator activities in many different transcription-regulating cell signaling pathways, and interference of TAF[II]135 activity by CAG repeats may be a common mechanism of specific types of neuropathologies.
