SF structure of CTD (C-terminal domain or MH2 domain) consists of a beta-sandwich with a three-helix bundle on one end and a collection of three large loops and an alpha-helix on the other [1];
SF CTD contains a primary homo-oligomerization activity [1];
SF a model of hetero-oligomerization is suitable from a structural perspective, in which a heterohexamer between Smad4 and Smad2 trimers is formed [1];
SF transcriptional activity is located in C-terminal domain [2];
SF interaction with JunB T01977 and c-Jun T00133 [8];
SF SAD domain (Smad4 activation domain) within the middle-linker region is essential for mediation of signaling responses [10];
SF NH2-terminal domain augments ligand-dependent activation associated with the middle-linker region, indicating a distinct ligand-response domain within the N terminus [10];
SF defective NLS (Nuclear Localization Signal) in comparison to R-Smads [11];
SF functional NLS (Nuclear Localization Signal) in its MH1 domain is required for the rapid transport to the nucleus, even in absence of TGF-beta [15];
SF Nuclear Export Signal (NES) in exon 3, a functional leucine-rich motif, actively directs nuclear export, which is necessary, but not sufficient for the nuclear export [12] [15];
SF SAD provides transcriptional capability by presenting proline-rich and glutamine-rich surfaces for interaction with transcription partners [13];
SF the structure implicates that sulfate-ion-binding sites are potential receptors for the phosphorylated sequence of R-SMADs in forming a heteromeric complex [13];
SF Smad4 (delta275-322) forms heteromeric complexes with Smad2 and undergoes ligand-dependent nuclear translocation in the presence of overexpressed Smad2 [9];
SF a preservation of the C-terminal structure is suggested in Smad4 (delta275-322) and indicated is the principal effect of SAD deletion is to interfere with the nuclear activities of Smad4 [9];
SF analysis of the genomic sequence reveals that any of the five exons between the end of the MH1 domain (exon 2) and the beginning of the MH2 domain (exon 8) can be deleted while maintaining the correct reading frame, T04554, T04555>, T04557, T04558, T04559>, T04560 [15];
SF interaction via the MH2 domain with an orphan transcriptional activator MSG1 [18];
SF enhancement of transcription by MSG1 depends on TGF-beta [18];

FF TGFbeta1 treatment increased the protein level [30];
FF LOX downregulates this protein [30];
FF nuclear translocation depends on receptor activated Smads, like Smad1 or Smad2 in response to BMP4 or TGF-beta [4];
FF it is surmised that activated Smads bind Smad4 in the cytoplasm and carry it into the nucleus [4];
FF forms a ternary complex with Smad1 and FoxH1(=FAST-1) in presence of TGF-beta [4];
FF transcriptional activation by the SAD is functionally dependent on p300, especially the N-terminus [9];
FF it appears that germ line mutations cannot account for many of the familial aggregations of pancreatic carcinoma [5];
FF important role in the development of gastrointestinal tumors [14];
FF this mutant form is predicted to be truncated at the C-terminus and lack sequences required for normal function [14];
FF a four base pair deletion was detected in exon 9, resulting in deletion of codons 414 to 416, causing a frameshift that creates a new stop codon at the end of exon 9, codon 434 [14];
FF the C-domain is required for the transcriptional activation by receptor-regulated Smads, like Smad1 and Smad2 [4];
FF sequences of exons 5, 6, and 7 are all required for full TGF-beta induced activation by Smad4 [15];
FF co-activation of PAI-1 promoter together with Smad3 T04431 and p300 [16];
FF in the absence of TGF-beta, SnoN (SKI-RELATED ONCOGENE SNO-N) binds to the nuclear Smad4 and represses TGF-beta responsive promoter activity through recruitment of a nuclear repressor complex [17];
FF TGF-beta induces activation and nuclear translocation of Smad2, Smad3 and Smad4 [17];
FF Smad3 causes degradation of SnoN, allowing a Smad2 and Smad4 complex to activate TGF-beta target genes [17];
