ANTI-PAR-4 (PROSTATE APOPTOSIS RESPONSE-4) RABBIT

Anti-Par-4 (Prostate Apoptosis Response-4) antibody produced in rabbit may be used in immunoblotting.

PRKC apoptosis WT1 regulator protein (PAWR) is also known as prostate apoptosis response 4 protein (Par-4). The PAWR gene is mapped to human chromosome 12q21.2. It is a 40 kDa protein expressed ubiquitously in mammals. It was first identified in prostate tumors.It has a leucine zipper domain and nuclear localization sequences. A core domain comprising of region 137-195 amino acids is critical for the apoptotic function of PAR-4. It interacts and modulates the activity of protein kinase C.

Par-4 protein interacts with Wilm′s tumor suppressor WT1 and modulates its transcription and growth suppression function. The gene for Par-4 is down-regulated by oncogenic Ras via the Raf-1- mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK-ERK) pathway in immortalized fibroblasts. Overexpression of the PAR4 gene causes down-regulation of B-cell lymphoma-2 (Bcl-2) in fibroblasts and prostate cancer cells. Par-4 protein plays an important role in neuronal apoptosis. This gene is upregulated in neuronal degeneration and is observed in Alzheimer′s disease.
