SCP3 (Synaptonemal complex protein 3) is a DNA-binding nuclear protein that belongs to XLR/SYCP3 family and is an essential structural component of the transverse filaments of synaptonemal complexes formed between homologous chromosomes during meiotic prophase. Synaptonemal complex develops during prophase of first meiosis, wherein it allows the synapse as well as recombination between maternal - paternal chromosome, and SCP3 is essential to hold cohesin complex between homologous chromosomes, which avoid premature segregation thereby preventing aneuploidies. SCP3 is involved in phosphorylation of HORMAD1 and HORMAD2. It is essential to development of testis (where it is primarily localized) and defective SCP3 may leads to spermatogenic failure type 4 (SPGF4). SCP3 deificient mouse depicts high numbers of aneuploidies in oocytes and offspring. SCP3 is also expressed in certain malignancies including human acute lymphatic leukemias, cervical cancer cells, lung cancer cells etc.
