PRRC2A (Proline rich coiled-coil 2A) functions as an m6A reader protein that plays critical roles in RNA metabolism and cellular regulation. The protein recognizes m6A-modified transcripts and regulates their stability and translation efficiency 12. In male reproductive biology, PRRC2A is essential for spermatogenesis, particularly for meiosis I completion, where it maintains proper spermatocyte expression patterns by downregulating spermatogonia-specific transcripts and enhancing translation of meiotic cell division genes 1. PRRC2A interacts with multiple proteins involved in mRNA metabolism including YBX1, YBX2, PABPC1, FXR1, and EIF4G3 1. In cancer biology, PRRC2A promotes colorectal cancer progression by stabilizing CSNK1E mRNA in an m6A-dependent manner, leading to activation of WNT and YAP signaling pathways 2. Genetic variants in PRRC2A have been associated with multiple diseases including B-cell non-Hodgkin lymphoma, where rs3132453 confers reduced risk 3, and type 1 diabetes, where rs2260051 increases disease susceptibility through enhanced PRRC2A expression 4. Additionally, PRRC2A shows sex-specific DNA methylation patterns in Alzheimer's disease 5 and has been identified as a potential biomarker for epilepsy 6.
