Biochem/physiol Actions

ABL127 is a potent and selective inhibitor of Protein phosphatase methylesterase-1 (PME-1 or PPME-1). IC50 values were 11.1 nM and 6.4 nM in MDA-MB-231 and HEK 293T cells with no activity detected against >50 other serine hydrolases. PME-1 regulates the methylesterification state of protein phosphatase 2A (PP2A) and is implicated in cancer and neurodegeneration.

Bone marrow-derived mesenchymal stem cells (BM-MSCs) are multipotent stem cells with ability to self-replicate and differentiate into mesodermal derivatives, such as adipocytes and osteoblasts. BM-MSCs are a critical component of the tumour microenvironment. They support tumour progression by recruiting additional

Reversible methyl-esterification (methylation) of Leu309 in the protein phosphatase 2A catalytic subunit (PP2Ac) is essential for proper biogenesis of the PP2A holoenzyme. Accumulating evidence links PP2Ac methylation to diseases, including cancer and neurodegenerative disorders. Protein phosphatase methyl-esterase (PME-1) specifically catalyzes
