Invitrogen™ DDX3/DDX3Y Recombinant Rabbit Monoclonal Antibody (1N2I8)

DDX3 (DEAD-box helicase 3) is an RNA helicase involved in multiple cellular processes, including RNA splicing, transport, translation, and degradation. It has key roles in antiviral responses, cell cycle regulation, and apoptosis. DDX3 is involved in the regulation of gene expression at multiple levels and is critical in processes such as cell cycle regulation, apoptosis, and innate immune response to viral infections. DDX3 has been shown to interact with various cellular proteins and RNA molecules, influencing their stability and function. DDX3Y, also known as DBY, belongs to the DEAD-box protein family and is located on the Y chromosome at Yq11.It shares significant sequence and functional similarity with DDX3 but has a more restricted expression pattern, predominantly in the testes. Mutations or deletions in DDX3Y can lead to male infertility due to impaired spermatogenesis. The protein encoded by DDX3Y consists of conserved motifs for ATP binding and hydrolysis necessary for RNA unwinding, making it vital for the proper translation and stability of mRNAs during spermatogenesis.
