Application

ML240 has been used as an inhibitor of D2 ATPase activity of valosin-containing protein.

Biochem/physiol Actions

ML240 is a selective, ATP-competetive inhibitor of AAA ATPase p97, also called valosine containing protein (VCP). The IC50 for p97 inhibition is 110 nM. ML240 rapidly induces activity of Caspases 3 and 7, leading to apoptosis. ML240 has potent antiproliferative activity towards NCI-60 cancer cell lines.

A major challenge of targeted cancer therapy is the selection for drug-resistant mutations in tumor cells leading to loss of treatment effectiveness. p97/VCP is central regulator of protein homeostasis and a promising anticancer target because of its vital role in

p97 is an ATPase that works in concert with histone deacetylase 6 (HDAC6), to facilitate the degradation of misfolded proteins by autophagosomes. p97 has also been implicated in DNA repair and maintaining genomic stability. In this study, we determined the

RNA binding proteins have been shown to play a key role in the pathogenesis of amyotrophic lateral sclerosis (ALS). Mutations in valosin-containing protein (VCP/p97) cause ALS and exhibit the hallmark nuclear-to-cytoplasmic mislocalization of RNA binding proteins (RBPs). However, the mechanism

During autophagy, vesicle dynamics and cargo recruitment are driven by numerous adaptors and receptors that become tethered to the phagophore through interactions with lipidated ATG8/LC3 decorating the expanding membrane. Most currently described ATG8-binding proteins exploit a well-defined ATG8-interacting motif (AIM
