REC8 is a meiosis-specific member of the cohesin protein family, essential for maintaining sister chromatid cohesion and ensuring accurate chromosome segregation during gamete formation. Structurally, it shares conserved domains with other cohesins, including N- and C-terminal regions critical for interactions with sister chromatids and regulatory partners. Unlike somatic cohesins (e.g., RAD21), REC8 is predominantly expressed in germline cells, where it forms a key component of the meiosis-specific cohesin complex. During prophase I, REC8 mediates axial element assembly, facilitates homolog pairing, and supports crossover formation by stabilizing recombination intermediates. Its stepwise removal—first from chromosome arms during anaphase I and later from centromeres in anaphase II—ensures sequential segregation of homologs and sister chromatids. Defects in REC8 function disrupt meiotic fidelity, leading to non-disjunction errors, aneuploidy (e.g., in Down syndrome), or premature ovarian failure. Studies in model organisms (e.g., mice, yeast) highlight its role in fertility, with REC8 mutations linked to human reproductive disorders. Recent research explores its interplay with shugoshin proteins and post-translational modifications (e.g., phosphorylation) regulating cohesion dynamics. As a biomarker for gamete quality, REC8 is a potential target for diagnosing or treating infertility and meiosis-related chromosomal abnormalities.
