Entrez gene summary
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 mediates the signal of the transforming growth factor (TGF)-beta, and thus regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. This protein is recruited to the TGF-beta receptors through its interaction with the SMAD anchor for receptor activation (SARA) protein. In response to TGF-beta signal, this protein is phosphorylated by the TGF-beta receptors. The phosphorylation induces the dissociation of this protein with SARA and the association with the family member SMAD4. The association with SMAD4 is important for the translocation of this protein into the nucleus, where it binds to target promoters and forms a transcription repressor complex with other cofactors. This protein can also be phosphorylated by activin type 1 receptor kinase, and mediates the signal from the activin. Alternatively spliced transcript variants have been observed for this gene.

The protein view displays protein features. The tabs at the top of the protein view section can be used to switch between the different splice variants encoded by this gene. The mouse over function displays additional data for the features in the protein view.
At the top of the protein view, the maximum percent sequence identity of the protein to all other proteins from other human genes is shown, using a sliding window of 10 aa residues
(HsID 10) or 50 aa residues (HsID 50) (read more).
If a signal peptide is predicted by a majority of the signal peptide predictors SPOCTOPUS,
SignalP 4.0, and
Phobius
(turquoise) and/or transmembrane regions (orange) are predicted by MDM, these are displayed.
Common (purple) and unique (grey) regions between different splice variants of the gene are also displayed
(read more), and at the bottom of the protein view is the protein scale.
The protein information section displays the alternative protein-coding transcripts (splice variants) encoded by this gene, according to the Ensembl database.
The ENSP identifier links to the Ensembl website protein summary, while the ENST identifier links to the Ensembl website transcript summary for the selected splice variant.
The data in the UniProt column can be expanded to show links to all matching
UniProt identifiers for this protein.
The protein classes to which this protein has been assigned are shown if expanding the data in the protein class column. Parent protein classes are in bold font and subclasses are listed under the parent class.
The Gene Ontology terms assigned to this protein are listed if expanding the Gene ontology column.
The length of the protein (amino acid residues according to Ensembl), molecular mass (kDalton), predicted signal peptide (according to a majority of the signal peptide predictors
SPOCTOPUS,
SignalP 4.0, and
Phobius) and the number of predicted transmembrane region(s) (according to
MDM) are also reported.
