Merck, 14-920, CLK1, active

General description
CLK1 is a 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.
Product Source: N-terminal 6His-tagged, recombinant, human CLK1, amino acids 130-end expressed by baculovirus in Sf21 insect cells
