CC -!- FUNCTION: Core component of the smc-5/smc-6 complex (PubMed:20661436).
CC Involved in DNA double-strand break repair by promoting sister-
CC chromatid homologous recombination during meiosis (PubMed:20661436,
CC PubMed:24939994, PubMed:27010650). Also plays a role in the DNA damage
CC repair of ultraviolet (UV) radiation-induced DNA lesions
CC (PubMed:24424777). Promotes efficient DNA replication
CC (PubMed:24424777). {ECO:0000269|PubMed:20661436,
CC ECO:0000269|PubMed:24424777, ECO:0000269|PubMed:24939994,
CC ECO:0000269|PubMed:27010650}.
CC -!- SUBUNIT: Interacts with smc-5. {ECO:0000269|PubMed:20661436}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:20661436}. Chromosome
CC {ECO:0000269|PubMed:20661436}. Note=Nucleoplasmic in the distal gonad
CC arm and localizes on chromosomes during pachytene, diplotene and
CC diakinesis in oocytes. {ECO:0000269|PubMed:20661436}.
CC -!- TISSUE SPECIFICITY: Expressed in the germline (at protein level).
CC {ECO:0000269|PubMed:20661436}.
CC -!- DEVELOPMENTAL STAGE: Expressed in the primordial germ cells Z2 and Z3
CC in embryos and in proliferating germ cells in L2/L3 stage larvae (at
CC protein level). {ECO:0000269|PubMed:24424777}.
CC -!- DOMAIN: The flexible hinge domain, which separates the large
CC intramolecular coiled coil regions, allows the heterotypic interaction
CC with the corresponding domain of smc-5, forming a V-shaped heterodimer.
CC {ECO:0000305}.
CC -!- DISRUPTION PHENOTYPE: Reduced fecundity and transgenerational sterility
CC (PubMed:20661436). Increased germ cell apoptosis and hypersensitivity
CC to ultraviolet and ionizing radiation and hydroxyurea-induced
CC replication stress (PubMed:20661436, PubMed:24424777). Increased rad-51
CC foci in the mitotic and meiotic germline on autosomes, but not on X
CC chromosomes (PubMed:20661436, PubMed:27010650, PubMed:24424777,
CC PubMed:24939994). Chromosome fragmentation defects and unresolved
CC diakinesis chromosomes in meiotic oocytes (PubMed:20661436,
CC PubMed:27010650). Impaired DNA replication in germ cells
CC (PubMed:24424777). Accumulation of brd-1 on chromosomes in mitotic germ
CC cells (PubMed:24424777). In a him-3 mutant background, increased rad-51
CC foci and chromosome fragmentation (PubMed:20661436). RNAi-mediated
CC knockdown of syp-2 leads to an increase of chromosome fragmentation
CC (PubMed:20661436). In a him-6 mutant background, leads to synergistic
CC lethality (PubMed:27010650). In a fem-3 or him-8 mutant background,
CC RNAi-mediated knockdown leads to increased fragmentation of autosomes
CC and asynapsed X chromosomes but not of X chromosomes in males
CC (PubMed:24939994). {ECO:0000269|PubMed:20661436,
CC ECO:0000269|PubMed:24424777, ECO:0000269|PubMed:24939994,
CC ECO:0000269|PubMed:27010650}.
CC -!- SIMILARITY: Belongs to the SMC family. SMC6 subfamily. {ECO:0000305}.
