Protein

Dual specificity protein kinase CLK3

Gene

CLK3

Organism

Homo sapiens (Human)

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex. May be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing and can cause redistribution of SR proteins from speckles to a diffuse nucleoplasmic distribution. Phosphorylates SRSF1 and SRSF3. Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells.2 Publications

Catalytic activityⁱ

ATP + a protein = ADP + a phosphoprotein.

Activity regulationⁱ

Leucettine L41 inhibits its kinase activity and affects the regulation of alternative splicing mediated by phosphorylation of SR proteins.
