High mobility group nucleosomal binding domain 2 pseudogene 4 (HMGN2P4)

High mobility group nucleosomal binding domain 2 pseudogene 4 (HMGN2P4) is a processed pseudogene in the human genome, related by sequence homology to the genuine gene HMGN2, which encodes a chromatin-associated protein involved in nucleosome binding and transcriptional regulation. Like other pseudogenes, HMGN2P4 does not encode a functional protein, and its biological roles—if any—remain largely uncharacterized. Although some pseudogenes modulate expression of their parent genes by acting as competing endogenous RNAs (ceRNAs), miRNA decoys, or regulators of mRNA stability, there are currently no specific publications documenting functional or pathological implications of HMGN2P4. It is not considered a druggable or therapeutic target.
