Maternal embryonic leucine zipper kinase (MELK)

Serine/threonine-protein kinase involved in various processes such as cell cycle regulation, self-renewal of stem cells, apoptosis and splicing regulation. Acts as an activator of apoptosis by phosphorylating and activating MAP3K5/ASK1.

Acts as a regulator of cell cycle, especially by mediating phosphorylation of CDC25B, promoting localization of CDC25B to the centrosome and the spindle poles during mitosis. Plays a key role in cell proliferation and carcinogenesis.
