Buy P21 Online. P21 is commonly known as Cyclin-dependent kinase inhibitor 1 (CDKN1A), a crucial protein in cell cycle regulation. It plays an important role in controlling cell growth and preventing uncontrolled cell division, which is vital for maintaining healthy tissue and preventing cancer. Buy P21 Online

Biological Function:

• Gene & Protein: The P21 protein is encoded by the CDKN1A gene. Buy P21 Online

• Cell Cycle Regulation: P21 inhibits cyclin-dependent kinases (CDKs), enzymes that promote cell cycle progression. By doing so, it causes cell cycle arrest, especially at the G1 phase.

• DNA Damage Response: When DNA damage occurs, P21 expression is upregulated, mainly through the activation of the tumor suppressor protein p53. This halts the cell cycle, allowing time for DNA repair. Buy P21 Online

• Tumor Suppression: Because of its role in halting cell proliferation in response to damage, P21 acts as a tumor suppressor and is a key player in preventing cancer. Buy P21 Online

Clinical Relevance:

• Cancer Research: Altered levels or mutations in P21 can lead to uncontrolled cell growth and cancer development.

• Therapeutic Target: P21 modulation is studied for cancer therapies aimed at controlling tumor growth or sensitizing cancer cells to chemotherapy. Buy P21 Online
