**Background of Recombinant Human CLK1 Protein**
The CDC-like kinase 1 (CLK1) is a member of the dual-specificity protein kinase family, regulating serine/arginine-rich (SR) protein phosphorylation, which is critical for pre-mRNA splicing, chromatin remodeling, and cellular signaling. CLK1 modulates spliceosome assembly by phosphorylating SR proteins, influencing alternative splicing events essential for diverse protein isoform generation. Dysregulation of CLK1 is linked to diseases like cancer, neurodegenerative disorders, and viral infections, highlighting its role in maintaining cellular homeostasis.
Recombinant human CLK1 protein is engineered via heterologous expression systems (e.g., *E. coli* or mammalian cells*) for functional and structural studies. Its production enables in vitro analysis of kinase activity, inhibitor screening, and mechanistic insights into splicing regulation. CLK1’s conserved kinase domain and unique N-terminal region make it a target for developing therapeutics, particularly for splicing-related pathologies. Studies using recombinant CLK1 have identified small-molecule inhibitors (e.g., TG003. cercosporamide) with potential in cancer and neurodegeneration. Research continues to explore its interplay with other kinases and non-splicing roles in metabolism and apoptosis. Overall, recombinant CLK1 serves as a vital tool for dissecting splicing mechanisms and advancing targeted drug discovery.
