CC -!- FUNCTION: Regulates the timing of initiation of DNA replication
CC (PubMed:29746464, PubMed:30277458, PubMed:26022086). Functions in copy
CC number control by promoting the underreplication of DNA, which is found
CC in many late replicating euchromatic regions of salivary gland polytene
CC chromosomes (PubMed:30277458). Promotes underreplication by localizing
CC to active DNA replication forks in a partially SuUR-dependent manner,
CC and inhibiting replication fork progression (PubMed:30277458). Might
CC also work as an adapter to recruit Pp1-87B to multiple sites on the
CC chromosome and may function with Pp1-87B to mediate underreplication
CC (PubMed:26022086, PubMed:29746464, PubMed:30277458). Plays an essential
CC role in embryonic development, in the transition from larvae to pupae
CC and, probably, in proliferating tissues later on (PubMed:26022086,
CC PubMed:29746464). In embryos, during mid-blastula transition, binds to
CC and selectively delays the replication of large blocks of repetitive
CC DNA satellite sequences during S phase in response to the activity of
CC Cdk1; maternal Rif1 is specifically required for the normal extension
CC of S phase 14 (PubMed:29746464). Unlike mammalian orthologs, does not
CC appear to play a role in DNA damage repair (PubMed:22712556,
CC PubMed:26022086). {ECO:0000269|PubMed:22712556,

CC ECO:0000269|PubMed:30277458}.
CC -!- SUBUNIT: Interacts with Pp1-87b (PubMed:26022086, PubMed:29746464).
CC Interacts with SuUR (via SNF2-like region) (PubMed:30277458).

CC ECO:0000269|PubMed:30277458}. Chromosome, telomere
CC {ECO:0000269|PubMed:26022086}. Note=Localizes to heterochromatin in all
CC stages of amplifying follicle cells and accumulates at active DNA
CC replication forks in the later stages of DNA amplification
CC (PubMed:30277458). Associates with polytene chromosomes in salivary
CC glands (PubMed:26022086). Associates with heterochromatin in a dynamic
CC manner in different mitotic stages of the cell cycle (PubMed:22712556,
CC PubMed:26022086, PubMed:29746464, PubMed:30277458). Absent at metaphase
CC chromosomes but re-associates with the condensed chromosomes during
CC late anaphase (PubMed:22712556, PubMed:26022086, PubMed:29746464).
CC During mid-blastula transition in the S phase of embryos, dissociates
CC from chromatin before the replication of the bound DNA satellite
CC sequences (PubMed:29746464). {ECO:0000269|PubMed:22712556,

CC -!- TISSUE SPECIFICITY: Expressed in nurse cells and follicle cells in the
CC adult female (at protein level) (PubMed:26022086, PubMed:30277458).
CC Detected in adult at extremely low levels (PubMed:26022086).
CC {ECO:0000269|PubMed:26022086, ECO:0000269|PubMed:30277458}.
CC -!- DEVELOPMENTAL STAGE: Expressed in embryos at high levels between 0-2
CC hours; from 8 to 14 hours, the highest levels are in the brain then
CC diminishes to negligible levels (at protein level) (PubMed:22712556,
CC PubMed:26022086, PubMed:29746464). Expressed in larval imaginal disks
CC and salivary glands (at protein level) (PubMed:26022086). Detected in
CC larvae at lower levels in imaginal disks, the central nervous system
CC and ovary and, at extremely low levels, in testis (PubMed:26022086).
CC {ECO:0000269|PubMed:22712556, ECO:0000269|PubMed:26022086,
CC ECO:0000269|PubMed:29746464}.
CC -!- PTM: Phosphorylated, probably by Cdk1; phosphorylation regulates
CC dissociation from heterochromatin. {ECO:0000269|PubMed:29746464}.
CC -!- DISRUPTION PHENOTYPE: Embryos have a reduced hatch rate and develop
CC into adults with reduced survival (PubMed:29746464). During mid-
CC blastula transition in embryos, S phase 14 is significantly shorter
CC (PubMed:29746464). In larval salivary glands, loss of DNA
CC underreplication resulting in abnormally enlarged chromocenters
CC (PubMed:30277458). RNAi-mediated knockdown results in lethality
CC (PubMed:26022086). Escaper flies only live for a few days and are
CC infertile (PubMed:26022086). Females show increased necrotic spots in
CC the abdominal segments (PubMed:26022086). RNAi-mediated knockdown in
CC the imaginal disks does not affect viability (PubMed:26022086).
CC {ECO:0000269|PubMed:26022086, ECO:0000269|PubMed:29746464,
CC ECO:0000269|PubMed:30277458}.
CC -!- SIMILARITY: Belongs to the RIF1 family. Highly divergent.
