Previous GeneCards Identifiers for CLK1 Gene
This gene encodes a member of the CDC2-like (or LAMMER) family of dual specificity protein kinases. In the nucleus, the encoded protein phosphorylates serine/arginine-rich proteins involved in pre-mRNA processing, releasing them into the nucleoplasm. The choice of splice sites during pre-mRNA processing may be regulated by the concentration of transacting factors, including serine/arginine rich proteins. Therefore, the encoded protein may play an indirect role in governing splice site selection. Multiple transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for CLK1 Gene
CLK1 (CDC Like Kinase 1) is a Protein Coding gene. Among its related pathways are Legionellosis and mRNA Splicing - Major Pathway. Gene Ontology (GO) annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is CLK4.
UniProtKB/Swiss-Prot Summary for CLK1 Gene
Dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex and may be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing. Phosphorylates: SRSF1, SRSF3 and PTPN1. Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells and adenovirus E1A pre-mRNA.
CLKs (Cdc2-like kinase) are dual specificity protein kinases which are involved in gene splicing regulation. The CLK family has four family members: CLK1/STY, CLK2, CLK3 and CLK4. CLKs are useful targets for studying diseases attributed to gene mis-splicing events.
