Background: Mammalian Sterile20-like kinase 2 (Mst2) is a serine/threonine kinase which represents a member of the germinal center kinases (GCKs), a family of ‘Sterile 20 (STE20) like kinases’. MST1 and MST2 are mammalian homologs of drosophila ‘Hpo’ playing a fundamental role in organ size control and tumor suppression. Both proteins share high sequence homology with identical N-terminal kinase domains and C-terminal SARAH (Salvador, RASSF and Hpo homology) domains, that mediates hetero- and homo-dimerisation. MST1/2 in conjunction with an adaptor protein Salvador phosphorylates and activates LATS1/2 kinases, finally results in an inhibition of cell proliferation and promotion of apoptosis. Furthermore, MST1/2 kinases have been implicated in immune regulation including T cell proliferation, activation, and homeostasis, lymphocyte chemotaxis and trafficking, as well as inflammatory responses.
