Cyclin L1 (CCNL1) is a member of the cyclin protein family, which plays regulatory roles in cell cycle progression and transcriptional elongation. Unlike canonical cyclins, CCNL1 lacks the typical cyclin box domain but contains conserved N-terminal cyclin-like folds and a C-terminal proline-rich region. It interacts with cyclin-dependent kinases (CDKs), particularly CDK11. to form complexes involved in modulating RNA polymerase II activity and pre-mRNA splicing. CCNL1 is ubiquitously expressed in human tissues, with high levels observed in the brain, heart, and testis. Functionally, it contributes to cell cycle control by influencing G1/S and G2/M phase transitions, apoptosis, and cellular differentiation. Dysregulation of CCNL1 has been linked to pathological conditions, including various cancers (e.g., hepatocellular carcinoma, breast cancer), where its abnormal expression correlates with tumor progression and patient prognosis. Additionally, CCNL1 interacts with viral proteins, potentially affecting host-cell responses during infections. Emerging studies suggest its involvement in DNA damage repair pathways and neurological disorders, though mechanistic details remain under investigation. As a regulator at the intersection of cell cycle control and transcriptional machinery, CCNL1 represents a potential therapeutic target, prompting ongoing research into its molecular functions and disease-associated pathways.
