General description

The X-linked androgen receptor (Dihydrotestosterone receptor; Nuclear receptor subfamily 3 group C member 4) is a member of the family of NR3 ligand-dependent transcription factors characterized by a ligand binding domain at the C-terminus, a central DNA-binding domain, and N-terminal transcription- activation domains. Androgen receptors are activated by steroid hormones such as testosterone and dihydrotestosterone. Activated androgen receptors translocate from the cytoplasm to the nucleus where they form homodimers that bind DNA. The androgen receptor associates with a number of adaptor-like proteins and functions as a complex that may induce or repress transcription depending on whether its associated proteins are co-activators or co-repressors that affect transcription possibly by modifying chromatin; co-activators are involved in histone acetylation and transcriptional activation whereas co-repressors are involved in histone deactylation and transcriptional repression. The androgen receptor is important for determining sex and male characteristics. Defective androgen receptors may play a role in Reifenstein syndrome, Kennedy disease, as well as prostate cancer.

Specificity

Detects Androgen Receptor (AR) only when phosphorylated on Ser81

Immunogen

KLH-conjugated synthetic peptide corresponding to amino acids including and surrounding Ser81 of human Androgen Receptor.

Application

Anti-phospho-Androgen Receptor (Ser81) Antibody is an antibody against phospho-Androgen Receptor (Ser81) for use in WB.

The androgen receptor (AR) plays an essential role in prostate cancer, and suppression of its signaling with androgen deprivation therapy (ADT) has been the mainstay of treatment for metastatic hormone-sensitive prostate cancer for more than 70 y. Chemotherapy has been

Androgen receptor (AR) and PI3K/AKT/mTORC1 are major survival signals that drive prostate cancer to a lethal disease. Reciprocal activation of these oncogenic pathways from negative cross talks contributes to low/limited success of pathway-selective inhibitors in curbing prostate cancer progression. We

Prostate cancer cell growth is dependent upon androgen receptor (AR) activation, which is regulated by specific kinases. The aim of the current study is to establish if AR phosphorylation by Cdk1 or ERK1/2 is of prognostic significance. Scansite 2.0 was

Despite increases in diagnostics and effective treatments, over 300,000 men die from prostate cancer highlighting the need for specific and differentiating biomarkers. AR phosphorylation associates with castrate-resistance, with pARser213 promoting transcriptional activity. We hypothesise that combined pARser81 and pARser213 reduces

Prostate cancer (PCa) remains the most diagnosed non-skin cancer amongst the American male population. Treatment for localized prostate cancer consists of androgen deprivation therapies (ADTs), which typically inhibit androgen production and the androgen receptor (AR).
