The two most C-terminal serine residues become phosphorylated and, together with a third, non-phosphorylated serine residue, form an evolutionarily conserved SSXS motif in all R-Smads.... TGF-b and activin receptors phosphorylate Smad2 and Smad3, and BMP receptors phosphorylate Smad1, Smad5 and Smad8 (Chen et al., 1998) (Fig. 1). The consequence of R-Smad phosphorylation is the formation of oligomeric complexes with the Co-Smad, Smad4."; prov:wasQuotedFrom pubmed:11792802 . sub:_6 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:11792802; prov:wasDerivedFrom beldoc:, sub:_5 . } sub:pubinfo { this: dcterms:created "2014-07-03T14:30:00.351+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
