SERTAD2 (SERTA Domain Containing 2): SERTAD2 is a multifunctional protein that contains a SERTA domain, which is linked to cell cycle regulation. In addition to its role in cell cycle progression, SERTAD2 participates in key cellular processes such as DNA replication, DNA repair, and chromatin remodeling. Its interactions with various transcription factors and co-regulators make it an important regulator of gene expression.
