F09A5.4 encodes one of three C. elegans proteins orthologous to members of the MOB (Mps One Binder) family of proteins, a group of highly conserved proteins that function as binding partners and co-activators of NDR/LATS protein kinases; in metazoans, MOB proteins are core components of the Hippo signaling pathway that regulates cell proliferation and survival.
Predicted to enable protein kinase activator activity. Predicted to be involved in positive regulation of protein phosphorylation and signal transduction. Predicted to be located in cytoplasm and nucleus. Is an ortholog of human MOB2 (MOB kinase activator 2).
