Subcellular location [CC]Cytoplasm {ECO:0000269|PubMed:15647271}. Nucleus {ECO:0000269|PubMed:15647271, ECO:0000269|PubMed:22781750}. Note=Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4 (PubMed:15647271). Co-localizes with LEMD3 at the nucleus inner membrane (PubMed:15647271). Exported from the nucleus to the cytoplasm when dephosphorylated (By similarity). {ECO:0000250|UniProtKB:P70340, ECO:0000269|PubMed:15647271}.
