Summaries for CLSPN Gene

Entrez Gene Summary for CLSPN Gene

  • The product of this gene is an essential upstream regulator of checkpoint kinase 1 and triggers a checkpoint arrest of the cell cycle in response to replicative stress or DNA damage. The protein is also required for efficient DNA replication during a normal S phase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

GeneCards Summary for CLSPN Gene

CLSPN (Claspin) is a Protein Coding gene. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle / Checkpoint Control. GO annotations related to this gene include anaphase-promoting complex binding.

UniProtKB/Swiss-Prot for CLSPN Gene

  • Required for checkpoint mediated cell cycle arrest in response to inhibition of DNA replication or to DNA damage induced by both ionizing and UV irradiation. Adapter protein which binds to BRCA1 and the checkpoint kinase CHEK1 and facilitates the ATR-dependent phosphorylation of both proteins. Can also bind specifically to branched DNA structures and may associate with S-phase chromatin following formation of the pre-replication complex (pre-RC). This may indicate a role for this protein as a sensor which monitors the integrity of DNA replication forks.

    • Interacts (phosphorylation-dependent) with CHEK1; regulates CLSPN function in checkpoint for DNA damage and replication. Interacts with ATR and RAD9A and these interactions are slightly reduced during checkpoint activation. Interacts with BRCA1 and this interaction increases during checkpoint activation. Interacts with TIMELESS.

Post-translational modifications for CLSPN Gene

  • Phosphorylated. Undergoes ATR-dependent phosphorylation by CHEK1 during activation of DNA replication or damage checkpoints. Phosphorylation by CSNK1G1/CK1 promotes CHEK1 binding.
  • Ubiquitinated by the anaphase promoting complex/cyclosome (APC/C) during G1 phase, leading to its degradation by the proteasome. Ubiquitination is mediated via its interaction with FZR1/CDH1. Following DNA damage, it is deubiquitinated by USP28 in G2 phase, preventing its degradation.
