H3 histone pseudogene 4 (H3P4)

H3 histone pseudogene 4 is a pseudogene located on human chromosome 1 (coordinates: 121,118,195-121,118,610, reverse strand)[3]. It was previously known by aliases such as HIST2H3DP1 and p05[3]. As a pseudogene, H3P4 does not encode a functional protein and its biological significance is limited; pseudogenes result from the accumulation of mutations in gene copies, rendering them non-functional. Unlike canonical histone genes, H3 histone pseudogene 4 is not involved in chromatin structure, epigenetic regulation, or any established cellular processes[2][5]. It does not have therapeutic relevance and is not considered a druggable or actionable biological target. There are no known interacting drugs, mechanisms of action, or associated biomarkers. Its classification as a histone-related pseudogene distinguishes it from other molecular families such as receptors, enzymes, or ion channels. If you need structured data on histone H3 proteins or histone H3 variants (such as H3.1, H3.2, H3.3, H3.4 (H3T), etc.), please specify, as those are functional proteins with relevant biological and disease roles[5].
