p53 Transcription Factor Activity Assay Kit

The tumor suppressor protein p53 is one of the key players in cancer biology. DNA damage and oxidative stress signals lead to p53 posttranslational modifications and stabilization by binding to its consensus sequence, the p53 response element. Stabilized p53 can interact with other transcriptional regulators for the induction of p53-responsive targets involved in cell cycle progression, cell senescence, or apoptotic cell death. Because the expression and activity of p53 are frequently altered in human cancers, p53 becomes an important drug target as well as a biomarker in carcinogenesis. BioVision’s p53 Transcription Factor Activity Assay Kit is a non-radioactive assay for the quantitative measurement of specific transcription factor DNA binding activity of active p53. A biotin-labeled p53 response element DNA binds specifically to active p53 in nuclear extract and forms a complex. The amount of complex is detected by the p53 specific monoclonal antibody using BioVision’s High-Sensitivity Streptavidin Plate. A HRP-conjugated secondary antibody provides a sensitive colorimetric readout at 450 nm using TMB as substrate.

Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation. Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells.The activation of transcription factor subunits is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerases. Transcription factors, unites and elongations can be RNA and DNA nucleic acids, base pairs of nucleotides . Converting from DNA to RNA is made by enzymatic reactions. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, anti-parallel RNA strand called a primary transcript. Transcriptions are key functions in signal transduction pathways. Signaling ligand binding transcription factors play an important role in transduction cascades.
