DEAD-box helicase 18 pseudogene 4 (DDX18P4)

DEAD-box helicase 18 pseudogene 4 (DDX18P4) is a pseudogene related to the DEAD-box helicase 18 gene. Pseudogenes are DNA sequences similar to functional genes but typically lack protein-coding ability or biological activity. The true protein-coding member, DEAD-box helicase 18 (DDX18), is an ATP-dependent RNA helicase involved in various cellular processes such as RNA secondary structure remodeling, transcription, nuclear and mitochondrial splicing, ribosome, and spliceosome assembly. DDX18 is implicated in pluripotency, cell growth, and is activated by Myc protein. Diseases associated with DDX18 include Bloom syndrome, but DDX18 itself is not currently considered a direct established therapeutic target in drug development[1][2][3][5]. Key clarification: - DDX18P4 itself is not an established therapeutic target; it is a pseudogene, and thus cannot be targeted by drugs or serve as a functional biomarker. The canonical molecular function and disease relevance pertain to the related protein-coding gene DEAD-box helicase 18 (DDX18), but not to DDX18P4[1].
