Subcellular Location: | Cytoplasm Nucleus Cytoplasmic and nuclear in the absence of TGF-beta On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4 (PubMed:15799969, PubMed:21145499) Through the action of the phosphatase PPM1A, released from the SMAD2:SMAD4 complex, and exported out of the nucleus by interaction with RANBP1 (PubMed:16751101, PubMed:19289081) Co-localizes with LEMD3 at the nucleus inner membrane (PubMed:15601644) MAPK-mediated phosphorylation appears to have no effect on nuclear import (PubMed:19218245) PDPK1 prevents its nuclear translocation in response to TGF-beta (PubMed:17327236) Localized mainly to the nucleus in the early stages of embryo development with expression becoming evident in the cytoplasm of the inner cell mass at the blastocyst stage (By similarity) |

Background: | The protein encoded by this gene belongs to the SMAD, a family of proteins similar to the gene products of the Drosophila gene 'mothers against decapentaplegic' (Mad) and the C elegans gene Sma SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways This protein functions as a transcriptional modulator activated by transforming growth factor-beta and is thought to play a role in the regulation of carcinogenesis |
