Serine/threonine-protein phosphatase PGAM5, mitochondrial (Pgam5)

Displays phosphatase activity for serine/threonine residues, and, dephosphorylates and activates MAP3K5 kinase. Has seemingly no phosphoglycerate mutase activity.

May be regulator of mitochondrial dynamics. Substrate for a KEAP1-dependent ubiquitin ligase complex.
