CCNA1 (cyclin A1)

Gene

• Entrez ID: 8900
• Gene name: Cyclin A1
• Gene symbol: CCNA1
• Synonyms: CT146
• Chromosome: 13
• Chromosome location: 13q13.3
• Summary: The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit
