This protein localizes mainly in the nucleus where it functions as an important component in the cellular response to DNA damage and replication stress. ATR detects DNA strand breaks and ssDNA coated with RPA and becomes activated to phosphorylate several downstream targets initiating the DNA damage response. High expression of ATR occurs in proliferative tissues emphasizing its role in cell cycle regulation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nATR plays an essential role in maintaining genomic stability. It is part of a larger protein complex that includes ATRIP (ATR-interacting protein) which helps in localizing ATR to sites of DNA damage. Once activated ATR phosphorylates various substrates including CHK1 a critical checkpoint kinase involved in cell cycle arrest during DNA repair processes. The ability of ATR to coordinate with these proteins helps cells manage DNA damage effectively and prevent genomic instability.\u003cbr\u003e\nPathways\u003cbr\u003e\nATR functions centrally in the DNA damage response and repair mechanisms particularly the ATR-Chk1 pathway. This pathway interacts closely with the ATM (Ataxia Telangiectasia Mutated) pathway which also responds to DNA damage but usually to double-strand breaks. ATR primarily acts in response to replication stress and its activation leads to the arrest of the cell cycle allowing DNA repair to occur. This cooperation between ATR and ATM highlights their complementary roles in safeguarding genomic integrity under stress.\u003cbr\u003e\nATR mutations and dysregulation have strong associations with cancer and Seckel syndrome. In the context of cancer ATR often works in concert with ATM to manage DNA repair and cancer cells frequently overexpress ATR to cope with high levels of replication stress. This makes ATR a potential target for cancer therapy where its inhibition could sensitize tumor cells to chemotherapy. In Seckel syndrome ATR mutations result in developmental anomalies showcasing the important role ATR plays in cellular replication and repair processes.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845108715689,"sku":"ab276104","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab276104","provider":"Iright","version":"1.0","type":"link"}
