RNA binding motif protein 17 pseudogene 4 (RBM17P4)

RNA binding motif protein 17 pseudogene 4 (RBM17P4) is a genomic DNA region classified as a *pseudogene* of the *RNA binding motif protein 17 (RBM17)* gene[2]. Unlike its parent gene RBM17, which encodes a splicing factor protein involved in mRNA splicing, RBM17P4 does not produce a functional protein and lacks evidence of biological or therapeutic relevance. There are no known protein products, functions, or disease associations attributed to RBM17P4 in current scientific resources[2]. **Key distinctions**: - RBM17 is an active, protein-coding gene involved in mRNA splicing, with alternative names including SPF45[1][5]. - RBM17P4 is a *pseudogene*: it is a non-functional copy related to RBM17, without evidence of expression or utility as a drug target[2]. Given the above, RBM17P4 should not be considered a drug discovery target, receptor, enzyme, transporter, or a molecule of therapeutic interest.
