Function

[MELK_MOUSE] Serine/threonine-protein kinase involved in various processes such as cell cycle regulation, self-renewal of stem cells, apoptosis and splicing regulation. Has a broad substrate specificity; phosphorylates BCL2L14, CDC25B, MAP3K5/ASK1 and ZNF622. Acts as an activator of apoptosis by phosphorylating and activating MAP3K5/ASK1. Acts as a regulator of cell cycle, notably 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. Required for proliferation of embryonic and postnatal multipotent neural progenitors. Phosphorylates and inhibits BCL2L14. Also involved in the inhibition of spliceosome assembly during mitosis by phosphorylating ZNF622, thereby contributing to its redirection to the nucleus. May also play a role in primitive hematopoiesis.^[1] ^[2]

Publication Abstract from PubMed

Murine protein serine/threonine kinase 38 (MPK38), also known as maternal embryonic leucine zipper kinase (MELK), has been associated with various human cancers and plays an important role in the formation of cancer stem cells. OTSSP167, a MELK selective inhibitor, exhibits a strong in vitro activity, conferring an IC50 of 0.41nM and in vivo effect on various human cancer xenograft models. Here, we report the crystal structure of MPK38 (T167E), an active mutant, in complex with OTSSP167 and describe its detailed protein-inhibitor interactions. Comparison with the previous determined structure of MELK bound to the nanomolar inhibitors shows that OTSSP167 effectively fits into the active site, thus offering an opportunity for structure-based development and optimization of MELK inhibitors.
