This protein is primarily expressed in the cytoplasm and mitochondria of various cell types including liver and kidney tissues. Mechanically p53R2 functions by reducing ribonucleotides into deoxyribonucleotides which are necessary for DNA synthesis and repair. This process is important for maintaining genomic stability especially under conditions of cellular stress or damage.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nP53R2 plays a role in the synthesis of deoxyribonucleotide triphosphates (dNTPs) for DNA repair. It forms part of a ribonucleotide reductase complex working with other subunits to ensure cells have sufficient dNTP pools for DNA replication and repair. The presence of p53R2 is integral for DNA damage response pathways where it gets activated to supply dNTPs during periods when the p53 tumor suppressor pathway senses DNA damage and activates DNA repair processes.\u003cbr\u003e\nPathways\u003cbr\u003e\nP53R2 is involved in DNA damage response and cell cycle regulation. It interacts with the tumor suppressor protein p53 especially during instances of genotoxic stress facilitating DNA repair and cell cycle arrest to prevent propagation of damaged DNA. Additionally p53R2 relates to proteins such as p21 which are components of the p53 pathway influencing cell cycle arrest and allowing time for DNA repair before cell division resumes.\u003cbr\u003e\nResearchers link p53R2 to cancer and mitochondrial depletion syndrome. In cancer mutations or dysregulated expression of p53R2 can impair DNA repair leading to genomic instability and tumorigenesis. The protein associates with p53 in these processes and its dysfunction may contribute to cancer progression. Furthermore mutations in p53R2 have implications in mitochondrial depletion syndrome where reduced functionality can affect mitochondrial DNA maintenance and cellular energy metabolism.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845099114665,"sku":"ab257215","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab257215","provider":"Iright","version":"1.0","type":"link"}
