SERTAD2 (SERTA Domain Containing 2): SERTAD2 is a multifunctional protein containing a SERTA domain, which is associated with cell cycle regulation. Beyond its role in cell cycle progression, SERTAD2 is involved in crucial cellular processes such as DNA replication, DNA repair, and chromatin remodelling. Its interactions with various transcription factors and co-regulators establish it as an important regulator of gene expression.
