Product details:
The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in the p53 network, including Chk2, p53R2, p53AIP1, Noxa, PIDD, PID/MTA2, MTBP and PERP, were identified and their genes were cloned recently. PERP, also termed PIGPC1 and THW, is a plasma membrane protein. p53 binds to the promoter of PERP and transcriptionally activates PERP gene then the translated PERP protein mediates the p53 induced apoptosis. The expression of PERP causes cell death. PERP is a mediator of p53 induced apoptosis. PERP has sequence similarity to PMP-22/gas3 and is a new member of the PMP-22/gas3 family.

PERP also known as P53 apoptosis effector related to PMP-22 is a protein with an approximate mass of 23 kDa. It mainly operates as an effector in the p53-dependent apoptosis pathway. PERP is known for facilitating cell-cell adhesion as a part of the desmosome complex. Researchers have found its expression primarily in epithelial tissues where it contributes to maintaining cell structure integrity. PERP's role is significant in tissues experiencing stress where it upregulates in response to p53 activation.
Biological function summary
PERP plays an active role in cellular processes like adhesion and apoptosis. As a part of the desmosome it helps in connecting epithelial cells. This function is important for preserving tissue architecture and responding to mechanical stress. PERP's involvement in apoptosis arises from its interactions in the p53 pathway supporting the process when cells require programmed death. These roles are essential for maintaining balanced cell proliferation and death key for tissue homeostasis.
Pathways
PERP is closely tied to the p53 pathway and the desmosomal adhesion process. The p53 pathway involves one of the primary tumor suppressor proteins and regulates the cell cycle while the desmosomal adhesion pathway maintains the structural cohesion between cells. PERP acts in concert with various proteins such as JUP (Plakoglobin) strengthening cellular adhesions and responding to apoptotic signals. This connectivity allows PERP to perform dual roles in maintaining cell stability and facilitating apoptosis when necessary.
PERP has associations with squamous cell carcinoma and epidermolysis bullosa. Disruption of PERP functions can lead to improper apoptosis contributing to cancer progression. In the case of epidermolysis bullosa alterations in desmosomal structure connected to PERP can weaken skin integrity leading to blistering. In these conditions proteins like JUP work alongside PERP highlighting the importance of balance between cell adhesion and controlled cell death in disease prevention.
