RNAi phenotypes: >90% embryonic lethality, HIM (11% males); loss of meiotic chromosome pairing and sister chromatid cohesion; meiotic nondisjunction; protein localizes to axes of chromosomes at meiotic prophase
rec-8 encodes a meiosis-specific cohesin complex subunit orthologous to Saccharomyces cerevisiae and Schizosaccharomyces pombe Rec8p; REC-8 is essential for pairing of homologoues and sister chromatids during meiosis and thus for proper chromosome disjunction; in the germline, REC-8 associates with chromatin of transition zone nuclei, and co-localizes with SMC-1 along the longitudinal axes of synapsed chromosomes at pachytene and in a cruciform pattern at diakinesis; REC-8 localization to chromatin is dependent upon TIM-1, a HEAT/Armadillo repeat-containing protein related to Drosophila TIMELESS, and additionally, REC-8 and SCC-3 are mutually required for chromatin localization; REC-8 cleavage and degradation during meiosis I is dependent on the AIR-2 aurora-like kinase and during meiosis II on AIR-2 and the PLK-1 polo-like kinase.
Predicted to enable chromatin binding activity and damaged DNA binding activity. Involved in double-strand break repair and organelle organization. Located in nuclear lumen and spindle. Part of chromatin. Expressed in Z2; Z3; embryonic cell; and gonad.
[J. Loidl] rec-8 (W02A2.6) is the likely ortholog of S. cerevisiae rec8 meiosis-specific cohesion protein

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
