PCBP3 (poly(rC) binding protein 3)

Gene

• Entrez ID: 54039
• Gene name: Poly(rC) binding protein 3
• Gene symbol: PCBP3
• Synonyms (NCBI Gene): ALPHA-CP3, PCBP3-OT1, PCBP3OT
• Chromosome: 21
• Chromosome location: 21q22.3
• Summary: This gene encodes a member of the KH-domain protein subfamily. Proteins of this subfamily, also referred to as alpha-CPs, bind to RNA with a specificity for C-rich pyrimidine regions. Alpha-CPs play important roles in post-transcriptional activities and h
