The MEI1 (Meiotic Ineptitude 1) protein is a critical regulator of meiosis, a specialized cell division process essential for gamete formation. In humans, MEI1 is encoded by the *MEI1* gene located on chromosome 22 (22q13.2). It plays a pivotal role in ensuring accurate chromosome segregation during meiosis, particularly in homologous recombination and the suppression of nonhomologous interactions. MEI1 deficiency disrupts meiotic progression, leading to chromosomal aberrations, infertility, or developmental defects, as observed in mouse models and clinical studies of human reproductive disorders.
Recombinant human MEI1 protein is produced using biotechnological platforms (e.g., bacterial, insect, or mammalian expression systems) to enable functional studies. Its purified form retains structural and biochemical properties, allowing researchers to investigate interactions with DNA, meiotic cofactors (e.g., REC8. SYCP3), and signaling pathways involved in gametogenesis. Structurally, MEI1 contains conserved domains critical for DNA binding and scaffold formation during synaptonemal complex assembly.
Research applications include elucidating molecular mechanisms underlying infertility, characterizing genetic mutations linked to reproductive disorders, and screening therapeutic targets. Additionally, recombinant MEI1 serves as a tool for studying aneuploidy-related conditions and refining CRISPR/Cas9-based genome-editing protocols in reproductive biology. Ongoing studies aim to link MEI1 dysregulation with broader implications in cancer and aging, emphasizing its multifaceted role in genomic stability.
