Ações bioquímicas/fisiológicas

Claspin is a protein which plays a major role in DNA replication. It involves in protecting DNA replication forks against DNA damage. In DNA damage response, claspin directly interacts with Rad17, which is required for ATR activation. ATR is activated by various DNA damage and DNA replication stress. Once activated, ATR (ataxia telangiectasia mutated-Rad3 related protein) phosphorylates effector kinase Chk1 which further depends on mediator protein claspin. Claspin helps to stimulate phosphorylation reaction of Chk1.

We have identified Claspin, a novel protein that binds to Xenopus Chk1 (Xchk1). Binding of Claspin to Xchk1 is highly elevated in the presence of DNA templates that trigger a checkpoint arrest of the cell cycle in Xenopus egg extracts.

Molecular and cellular biology, 26(16), 6056-6064 (2006-08-02)
TopBP1 and Claspin are adaptor proteins that facilitate phosphorylation of Chk1 by the ATR kinase in response to genotoxic stress. Despite their established requirement for Chk1 activation, the exact way in which TopBP1 and Claspin control Chk1 phosphorylation remains unclear.

Cell cycle (Georgetown, Tex.), 11(14), 2711-2716 (2012-06-27)
Claspin is a key mediator of the ATR-Chk1 checkpoint pathway. In response to DNA damage, Claspin interacts with Rad17 and Chk1 in a phosphorylation-dependent manner, enabling ATR to phosphorylate Chk1 efficiently. Claspin also interacts with Rad9, but how they interact
Yasunori Fukumoto et al.
The Journal of biological chemistry, 289(18), 12313-12329 (2014-03-19)
The DNA damage checkpoint arrests cell cycle progression to allow time for repair. Once DNA repair is completed, checkpoint signaling is terminated. Currently little is known about the mechanism by which checkpoint signaling is terminated, and the disappearance of DNA
