SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis
Cell Proliferation, EarlyView.The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...
