Target intelligence / Profile preview

Protein kinase Plasmodium falciparum CLK3 (PfCLK3)

Target
PfCLK3
Molecular classification
Protein Kinase, Cyclin-dependent like kinases (CLKs), Serine/Threonine Kinase
01

Overview

Protein kinase PfCLK3 is an essential regulator of RNA splicing required for malaria parasite viability at multiple life stages—including blood, liver, and sexual forms—and represents a highly promising target for next-generation antimalarials with both treatment and transmission-blocking capabilities.

Other names
PF3D7_1114700Plasmodium falciparum Cyclin-dependent Like Kinase 3
02

Mechanism of action

Inhibition of PfCLK3 leads to impaired phosphorylation of SR proteins, disrupted mRNA processing/splicing, and downregulation of essential genes.
