CD99 molecule pseudogene 1 (CD99P1)

CD99 molecule pseudogene 1 (CD99P1, also referred to as MIC2R or CD99L1) is a processed pseudogene located in the pseudoautosomal region of the human X and Y chromosomes[3]. It is related to the CD99 gene (also called MIC2), which encodes a cell surface glycoprotein with known roles in cell adhesion, migration, apoptosis, immune regulation, and cancer biology[1][2][3]. The CD99P1 gene itself does not appear to encode a functional protein and has no well-characterized biological function or disease involvement[3]. Transcripts from the *MIC2R* locus (another synonym for CD99P1) are detected in multiple human tissues, but none have been shown to produce a functional open reading frame[3]. Unlike protein-coding genes, there is no evidence that CD99P1 acts as a canonical receptor, enzyme, transporter, or therapeutic target. Its classification is "pseudogene," signifying a non-functional genomic element derived from a parent gene. CD99P1 (CD99 molecule pseudogene 1) should not be confused with CD99 (the protein-coding gene and molecule), which is a multifunctional cell surface protein implicated in cell adhesion, migration, apoptosis, and a variety of disease contexts, especially in cancer and immune regulation[1][2][3][4]. All functional and disease-associated information referenced in molecular biology literature pertains to CD99, not to CD99P1. If you require structured data for the functional CD99 protein, please specify "CD99" and not "CD99P1" or "CD99 molecule pseudogene 1."
