Activity summary

ATRIP also known as ATRIP protein serves as an essential component within the ATR-ATRIP complex which is vital in the DNA damage response. ATRIP is a protein that weighs approximately 86 kDa and is most commonly expressed in the nucleus of cells. It functions primarily by binding to ATR (Ataxia Telangiectasia and Rad3-related protein) which enables the ATR to localize to sites of DNA damage and replication stress. This enables the recognition and repair of damaged DNA preventing genomic instability.

Biological function summary

ATRIP plays roles in maintaining genome integrity. It forms a stable complex with ATR which is important for the activation of ATR kinase activity. ATRIP directly interacts with single-stranded DNA coated by replication protein A (RPA) to perform its functions. By facilitating ATR recruitment to DNA damage sites ATRIP aids in the initiation of DNA repair mechanisms which are critical for normal cellular function and survival.

Pathways

ATRIP's activities are an integral part of the DNA damage signaling and repair pathways. ATR-ATRIP complex is central to the DNA replication checkpoint pathway where it maintains replication fork stability and controls cell cycle progression. Additionally ATRIP is involved in pathways alongside proteins like CHK1 which it helps to activate in response to DNA damage ensuring proper cell cycle arrest and repair processes.

Associated diseases and disorders

ATRIP is implicated in certain cancers and genomic instability syndromes. Deficient ATRIP function can correlate with a higher predisposition to cancers due to defective DNA damage response and repair. Further the ATR-ATRIP interaction can influence the onset and progression of Seckel syndrome where defects in ATRIP or its partner ATR might lead to developmental abnormalities. The role of ATRIP in these diseases highlights the importance of maintaining genomic stability through effective DNA repair mechanisms.
