H3 histone pseudogene 22 (H3P22)

H3 histone pseudogene 22 (abbreviated H3P22) is classified as a pseudogene related to the histone H3 family. Pseudogenes are genetic elements that resemble protein-coding genes but typically lack the ability to produce functional proteins due to mutations or truncations. The name implies homology with the canonical histone H3 family, whose functional members (such as H3.1, H3.2, and the variant H3.3) are core structural proteins involved in chromatin organization, epigenetic regulation, and DNA packaging in all eukaryotic cells[1][2][3]. However, H3 histone pseudogene 22 itself does not encode a functional histone protein and is not represented among active histone genes or variants described in comprehensive reviews of the H3 gene family[1][2][3]. There is no established biological function, disease association, or therapeutic relevance for this pseudogene.
