Gene Snapshot

sisters on the loose (solo) encodes a chromosome protein involved in the meiotic sister chromatid cohesion pathway. It is required for sister centromere cohesion in both male and female meiosis and for maintenance of synaptonemal complexes and normal levels of homolog crossing-over in female meiosis.
