Function
Core component of the SHOC2-MRAS-PP1c (SMP) holophosphatase complex that regulates activation of the MAPK pathway (PubMed:10783161, PubMed:16630891, PubMed:25137548, PubMed:35768504, PubMed:35830882, PubMed:35831509, PubMed:36175670). Acts as a scaffolding protein in the SMP complex (PubMed:35768504, PubMed:35830882, PubMed:35831509, PubMed:36175670). The SMP complex specifically dephosphorylates the inhibitory phosphorylation at 'Ser-259' of RAF1 kinase, 'Ser-365' of BRAF kinase and 'Ser-214' of ARAF kinase, stimulating their kinase activities (PubMed:10783161, PubMed:16630891, PubMed:35768504, PubMed:35830882, PubMed:35831509, PubMed:36175670). The SMP complex enhances the dephosphorylation activity and substrate specificity of PP1c (PubMed:35768504, PubMed:36175670). Acts as an inhibitor of keratinocyte differentiation via interaction with RAS protein complexes that promote ERK activation (PubMed:23524970)
