Anti-REC8 Antibody Picoband® Fluoro488 Conjugated

Product Specifications

Background

Meiotic recombination protein REC8 homolog is a protein that in humans is encoded by the REC8 gene. It is mapped to 14q12. 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.

Meiotic recombination protein REC8 homolog; Cohesin Rec8p; REC8; REC8L1

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.
