PDEF (prostate-derived Ets factor) is a 37.5-kD protein that acts as an androgen-independent transcriptional activator for the PSA (prostate specific antigen) promoter.
It also interacts directly with the DNA binding domain of androgen receptor and enhances androgen-mediated activation of the PSA promoter.
PDEF was shown to have transcript levels 192-fold higher in the peripheral blood of some breast cancer patients in comparison with normal individuals.
PDEF mRNA is alsofrequently over-expressed in human breast tumors as well as in human ovarian tumors.
In ovarian tumors, PDEF expression seems to down-modulate malignant potential, and thus provides a rationale to screen for drugs that induce PDEF expression in epithelial ovarian tumors.

仕様
Size：100ul
Host：rabbit
Source Antibody：human
Grade：Purified
Purity：Purified by epitope affinity chromatography.
Form：Supplied as a liquid in PBS, pH 7.2. No preservatives added. Labeled with Biotin.
Specificity：Specific for human PDEF. On Western blots, it identifies a single band at ~37.5kD using LNCAP lysates. There is also a weak band at ~55kD which may be due to the glycosylated form of PDEF. Reactivity has been confirmed with human LNCAP prostate carcinoma cell lysates.
