Summary

REC8 (REC8 meiotic recombination protein, HGNC:16879) is a protein-coding gene on chromosome 14q12, encoding Meiotic recombination protein REC8 homolog (O95072). Required during meiosis for separation of sister chromatids and homologous chromosomes.

This gene encodes a member of the kleisin family of SMC (structural maintenance of chromosome) protein partners. The protein localizes to the axial elements of chromosomes during meiosis in both oocytes and spermatocytes. In the mouse, the homologous protein is a key component of the meiotic cohesion complex, which regulates sister chromatid cohesion and recombination between homologous chromosomes. Multiple alternatively spliced variants, encoding the same protein, have been found for this gene.

Function. Required during meiosis for separation of sister chromatids and homologous chromosomes. Proteolytic cleavage of REC8 on chromosome arms by separin during anaphase I allows for homologous chromosome separation in meiosis I and cleavage of REC8 on centromeres during anaphase II allows for sister chromatid separation in meiosis II.

Subunit / interactions. Interacts (phosphorylated and unphosphorylated form) with SMC3. Interacts with SYCP3. Interacts (phosphorylated and unphosphorylated form) with SMC1B. Does not interact with SMC1A. Interacts with RAD51. Forms a complex with EWSR1, PRDM9, SYCP3 and SYCP1; complex formation is dependent of phosphorylated form of REC8 and requires PRDM9 bound to hotspot DNA; EWSR1 joins PRDM9 with the chromosomal axis through REC8.

Subcellular location. Nucleus. Chromosome. Centromere.

Tissue specificity. Expressed in testis and thymus. Expressed in the B-cell lines WI-L2-NS and Namalwa (at protein level).

Post-translational modifications. Phosphorylated.

Similarity. Belongs to the rad21 family.
