General annotation (Comments)
| Function | Required for checkpoint mediated arrest of cell cycle progression in response to DNA damage during S-phase (the intra-S-phase checkpoint). This checkpoint requires activation of at least 2 parallel pathways by the ATM kinase: one involves the MRN (MRE11A-RAD50-NBS1) complex, while the second requires CHEK2. RIF1 seems to act independently of both these pathways. Seems to play no role in either the G1/S or G2/M DNA damage checkpoints By similarity. |
| Subunit structure | A fraction of the protein may interact with TRF2. |
| Subcellular location | Nucleus. Telomere. Note: Exhibits ATM- and TP53BP1-dependent localization to uncapped or aberrant telomeres and to DNA double strand breaks (DSBs). Localizes to microtubules of the midzone of the mitotic spindle during anaphase, and to condensed chromosomes in telophase By similarity. While the majority of the protein appears nuclear and distinct from normal telomere structures, a small fraction may bind to telomeres in embryonic stem cells. |
| Tissue specificity | Expressed in Sertoli cells, prospermatagonia, early primary spermatocytes, and in oocytes at all stages of their growth. Expressed in embryonic stem (ES) and embryonic germ (EG) cells: expression is lost upon differentiation. Ref.1 |
| Developmental stage | Found in the nucleus of germinal-vesicle (GV) stage oocytes prior to fertilization. Accumulates in the male and female pronucleus after fertilization. Expressed in the nuclei of all blastomeres from the two cell stage to the compacted morula stage, although absent from the polar body and inner cell mass (ICM). Found in the nuclei of polar and mural trophectoderm cells from E3.5, and at high levels in the epiblast from E5.5 to E7.5. Expressed by primitive germ cells (PGCs) in both male and female from E9.5 to E13.5, at which point expression declines. A low level is observed in Sertoli cells of the testis at E17.5. Ref.1 |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR By similarity. |
| Sequence caution | The sequence BAC38846.1 differs from that shown. Reason: Miscellaneous discrepancy. Chimeric cDNA. The sequence BAC40506.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention. |

Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q6PR54-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q6PR54-2) The sequence of this isoform differs from the canonical sequence as follows: 2198-2223: Missing. | ||||||
| Isoform 3 (identifier: Q6PR54-3) The sequence of this isoform differs from the canonical sequence as follows: 167-167: I → ISHWFLHC | ||||||
| Note: May be due to a competing acceptor splice site. No experimental confirmation available. |
