Ligand Sp. Action Value Parameter Reference
apilimod Hs Inhibition 7.2 pKd 1
pKd 7.2 (Kd 6.5x10-8 M) [1]
Description: Binding constant for Cy5-apilimod to PIKfyve kinase domain.
apilimod Hs Inhibition 7.8 pIC50 1
pIC50 7.8 (IC50 1.4x10-8 M) [1]
Description: Effect of apilimod on hPIKfyve kinase activity in vitro measuringPI(3)P conversion to PI(3,5)P2.
Immunopharmacology Comments
PIKfyve is a class III PI kinase. Evidence is revealing a crucial role for PIKfyve in Toll-like receptor (TLR) signaling via production of the cytokines IL-12 and IL-23 [1]. Pharmacological (using apilimod) or genetic inactivation of PIKfyve suppresses expression of the p40 (IL-12B) subunit shared by IL-12 and IL-23, and this has a regulatory role on TLR signaling.
Clinically-Relevant Mutations and Pathophysiology
Disease:  Corneal dystrophy, Fleck
Description: A rare, autosomal dominant disease which causes the formation of numerous tiny, dot-like white flecks scattered in all layers of the corneal stroma. A few patients present with photophobia, but the majority are asymptomatic.
Synonyms: CFD
corneal dystrophy, Francois-Neetens speckled ro flecked
OMIM: 121850

Type Species Amino acid change Nucleotide change Description Reference
Frameshift: Deletion Human 4166_4169delAAGT or 4167_4170delAGTA This mutation deletes 4 nucleotides in exon 24 of the gene, leading to a truncated protein product. 3
Missense Human K1103R 3466A>G 4
General Comments
Pharmacological inhibition of PIKfyve by apilimod (STA-5326) has potent cytotoxic activity against B-cell non-Hodgkin lymphoma cells [2]. This effect is selective for the lymphoma cells compared to normal cells.
