UniprotKB/SwissProt ID: RIF1_HUMAN (Q5UIP0)
Gene Name: RIF1
Organism: Homo sapiens (Human).
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.

Protein Subcellular Localization: Nucleus. Chromosome, telomere. Cytoplasm, cytoskeleton, spindle. Note=Exhibits ATM- and TP53BP1-dependent localization to uncapped or aberrant telomeres and to DNA double strand breaks (DSBs). Does not associate with normal telomere structures. Localizes
