Is an ortholog of human PDP1 (pyruvate dehyrogenase phosphatase catalytic subunit 1) and PDP2 (pyruvate dehyrogenase phosphatase catalytic subunit 2). Is predicted to have [pyruvate dehydrogenase (lipoamide)] phosphatase activity and magnesium-dependent protein serine\/threonine phosphatase activity. Human ortholog(s) of this gene are implicated in pyruvate decarboxylase deficiency.
