Heterogeneous nuclear ribonucleoprotein A1 pseudogene 66 (HNRNPA1P66)

Heterogeneous nuclear ribonucleoprotein A1 pseudogene 66 (HNRNPA1P66) is a processed pseudogene of the gene encoding heterogeneous nuclear ribonucleoprotein A1 (HNRNPA1). HNRNPA1 is a member of the hnRNP A/B protein family, which regulates mRNA splicing, stabilizes transcripts, and plays roles in gene expression, cellular stress response, and neurodevelopment[1][2][3][5]. However, HNRNPA1P66 itself does not encode functional protein, and pseudogenes like HNRNPA1P66 usually arise from duplication or retrotransposition events and are characterized by loss of coding potential due to accumulated mutations[1][7][4]. While some pseudogenes have been shown in rare cases to affect gene regulation, no functional or disease-related role is established for HNRNPA1P66, nor is it considered a drug target or a disease biomarker[7][4]. Key points: HNRNPA1P66 is a pseudogene; it does not encode a functional protein. It is not considered a therapeutic target, receptor, enzyme, transporter, or transcription factor. There is no evidence of disease association, biomarker utility, or drug interaction. If you are seeking information about the functional RNA-binding protein, the relevant gene is HNRNPA1, not the pseudogene HNRNPA1P66[5].
