Maternal embryonic leucine zipper kinase (MELK) is an enzyme that in humans is encoded by the MELK gene.[1][2][3] MELK is a serine/threonine kinase belonging to the family of AMPK/snf1 protein kinases. MELK was first identified present as maternal mRNA in mouse embryos.[4] MELK has been shown to involved in progression through the cell cycle, possibly linked to its interaction with CDC25B.[5] MELK expression is elevated in a number of cancers and is an active research target for pharmacological inhibition.[6]

Interactions

MELK has been shown to interact with CDC25B.[7]
