General annotation (Comments)
| Function | Essential for sustained cell growth, maintenance of chromosomal stability, and ATR-dependent checkpoint activation upon DNA damage. Has a weak ATPase activity required for binding to chromatin. Participates in the recruitment of the RAD1-RAD9-HUS1 complex and RHNO1 onto chromatin, and in CHEK1 activation. May also serve as a sensor of DNA replication progression, and may be involved in homologous recombination. Ref.7 Ref.18 Ref.20 Ref.21 Ref.23 Ref.25 Ref.26 Ref.27 Ref.28 Ref.29 Ref.31 |
| Subunit structure | Part of a DNA-binding complex containing RFC2, RFC3, RFC4 and RFC5. Interacts with RAD1 and RAD9 within the RAD1-RAD9-HUS1 complex. Interacts with RAD9B, POLE, NHP2L1 and MCM7. DNA damage promotes interaction with ATR or ATM and disrupts interaction with the RAD1-RAD9-HUS1 complex. Ref.2 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.22 Ref.24 Ref.25 Ref.26 Ref.27 Ref.28 |
| Subcellular location | Nucleus. Note: Phosphorylated form redistributes to discrete nuclear foci upon DNA damage. Ref.4 Ref.16 Ref.21 Ref.22 |
| Tissue specificity | Overexpressed in various cancer cell lines and in colon carcinoma (at protein level). Isoform 2 and isoform 3 are the most abundant isoforms in non irradiated cells (at protein level). Ubiquitous at low levels. Highly expressed in testis, where it is expressed within the germinal epithelium of the seminiferous tubuli. Weakly expressed in seminomas (testicular tumors). Ref.2 Ref.4 Ref.6 Ref.7 Ref.9 |
| Induction | Isoform 1, isoform 3 and isoform 4 are induced by X-ray irradiation. Ref.9 |
| Post-translational modification | Phosphorylated. Phosphorylation on Ser-646 and Ser-656 is cell cycle-regulated, enhanced by genotoxic stress, and required for activation of checkpoint signaling. Phosphorylation is mediated by ATR upon UV or replication arrest, whereas it may be mediated both by ATR and ATM upon ionizing radiation. Phosphorylation on both sites is required for interaction with RAD1 but dispensable for interaction with RFC3 or RFC4. Ref.18 Ref.20 Ref.21 Ref.25 |
| Sequence similarities | Belongs to the rad17/RAD24 family. |
