CDC2L1 (Cell Division Cycle 2-Like 1), also known as CRKRS or CDK11. is a member of the cyclin-dependent kinase (CDK) family, which plays critical roles in cell cycle regulation, transcriptional modulation, and RNA splicing. It is encoded by the CDC2L1 gene located on human chromosome 1p36.3. The protein exists as multiple splice variants, with CDK11⁰ (110 kDa) and CDK11p⁵⁸ (58 kDa) being the most studied isoforms. CDK11 forms a complex with cyclin L and is involved in phosphorylating substrates essential for RNA polymerase II-mediated transcription, pre-mRNA splicing, and mitotic progression.
Recombinant human CDC2L1 protein is produced using expression systems (e.g., E. coli, insect, or mammalian cells) to enable functional studies. Its recombinant form retains kinase activity and is widely used to investigate mechanisms underlying transcriptional elongation, spliceosome assembly, and cell cycle checkpoints. Dysregulation of CDC2L1 has been linked to cancers, neurodevelopmental disorders, and viral infections, making it a potential therapeutic target. Research utilizing recombinant CDC2L1 has also focused on identifying kinase inhibitors for drug development and elucidating its role in DNA damage response. Recent studies highlight its interaction with survival motor neuron (SMN) proteins, suggesting relevance in spinal muscular atrophy. Advances in structural biology using recombinant CDC2L1 have aided in mapping its catalytic domain and understanding substrate specificity. However, functional redundancy within CDK family members and splice variant complexity remain challenges in dissecting its precise physiological roles.
