Supplementary information

Rad53 also known as Chk2 is a serine/threonine-protein kinase with a molecular mass of approximately 89 kDa. It plays an essential role in the DNA damage response. It is primarily expressed in the nucleus of eukaryotic cells. Rad53 phosphorylates substrates involved in the cell cycle and DNA repair processes. This protein acts as a signal transducer in the DNA damage checkpoint pathway helping to maintain genomic stability.
Biological function summary

Rad53 regulates the cell cycle by mediating the response to DNA damage. It is part of the conserved cell cycle checkpoint signaling network. This protein interacts with several other checkpoint proteins including Mec1 and Tel1. It modulates the replication fork stabilization and recovery during DNA replication stress. The ability of Rad53 to detect and respond to DNA damage events is key for proper cell cycle progression and the prevention of chromosomal aberrations.

Pathways

Rad53 remains a central component of the DNA damage checkpoint pathway and the replication checkpoint pathway. Rad53 works closely with Mec1 which is an upstream kinase that activates Rad53 in response to DNA damage. The pathway involves other proteins like Dun1 and Sml1 which Rad53 regulates to initiate a proper cellular response. By engaging in these pathways Rad53 contributes to DNA repair and replication fork stability.

Rad53 plays a critical role in cancer and genetic instability disorders. Dysfunctional Rad53 activity can lead to unchecked cell proliferation contributing to the development of cancer. It interacts with proteins such as p53 which is often mutated in cancers. Mutations affecting Rad53 or its associated signaling pathway components can lead to reduced DNA repair capacity increasing susceptibility to genomic instability disorders.

Target data

Controls S-phase checkpoint as well as G1 and G2 DNA damage checkpoints. Phosphorylates proteins on serine, threonine, and tyrosine. Prevents entry into anaphase and mitotic exit after DNA damage via regulation of the Polo kinase CDC5. Seems to be involved in the phosphorylation of RPH1.
