Genet. 43:121-126(2011). CC -!- FUNCTION: Receptor-regulated SMAD (R-SMAD) that is an intracellular CC signal transducer and transcriptional modulator activated by TGF-beta CC (transforming growth factor) and activin type 1 receptor kinases. Binds CC the TRE element in the promoter region of many genes that are regulated CC by TGF-beta and, on formation of the SMAD3/SMAD4 complex, activates CC transcription. Also can form a SMAD3/SMAD4/JUN/FOS complex at the AP- CC 1/SMAD site to regulate TGF-beta-mediated transcription. Has an CC inhibitory effect on wound healing probably by modulating both growth CC and migration of primary keratinocytes and by altering the TGF-mediated CC chemotaxis of monocytes. This effect on wound healing appears to be CC hormone-sensitive. Regulator of chondrogenesis and osteogenesis and CC inhibits early healing of bone fractures. Positively regulates PDPK1 CC kinase activity by stimulating its dissociation from the 14-3-3 protein CC YWHAQ which acts as a negative regulator. {ECO:0000269|PubMed:10995748, CC ECO:0000269|PubMed:15241418, ECO:0000269|PubMed:15588252, CC ECO:0000269|PubMed:16156666, ECO:0000269|PubMed:16751101, CC ECO:0000269|PubMed:16862174, ECO:0000269|PubMed:17327236, CC ECO:0000269|PubMed:19218245, ECO:0000269|PubMed:19289081, CC ECO:0000269|PubMed:9732876, ECO:0000269|PubMed:9892009}. CC -!- SUBUNIT: Monomer; in the absence of TGF-beta (PubMed:9670020). CC Homooligomer; in the presence of TGF-beta (PubMed:9670020). CC Heterotrimer; forms a heterotrimer in the presence of TGF-beta CC consisting of two molecules of C-terminally phosphorylated SMAD2 or CC SMAD3 and one of SMAD4 to form the transcriptionally active CC SMAD2/SMAD3-SMAD4 complex (PubMed:11224571, PubMed:15350224, CC PubMed:15799969, PubMed:9670020). Part of a complex consisting of CC MAGI2/ARIP1, ACVR2A, ACVR1B and SMAD3 (PubMed:9892009). Forms a complex CC with SMAD2 and TRIM33 upon addition of TGF-beta (PubMed:16751102). CC Found in a complex composed of SMAD3, RAN and XPO4; within the complex CC interacts directly with XPO4 (PubMed:16449645). Component of the CC multimeric complex SMAD3/SMAD4/JUN/FOS which forms at the AP1 promoter CC site; required for synergistic transcriptional activity in response to CC TGF-beta (PubMed:10995748, PubMed:9732876). Part of a ternary complex CC composed of SMAD3, ITCH/AIP4 and NEDD9/HEF1; within the complex CC NEDD9/HEF1 interacts (via N-terminus) with ITCH/AIP4; the complex CC mediates ubiquitination and proteasomal degradation of NEDD9/HEF1 CC (PubMed:15051726). Interacts with NEDD9; the interaction promotes NEDD9 CC ubiquitination and proteasomal degradation (PubMed:15051726). Interacts CC (via an N-terminal domain) with JUN (via its basic DNA binding and CC leucine zipper domains); this interaction is essential for DNA binding CC and cooperative transcriptional activity in response to TGF-beta CC (PubMed:10995748, PubMed:9732876). Identified in a complex that CC contains at least ZNF451, SMAD2, SMAD3 and SMAD4 (PubMed:24324267). CC Interacts with PPM1A; the interaction dephosphorylates SMAD3 in the C- CC terminal SXS motif leading to disruption of the SMAD2/3-SMAD4 complex, CC nuclear export and termination of TGF-beta signaling (PubMed:16751101). CC Interacts (via MH2 domain) with ZMIZ1 (via SP-RING-type domain); in the CC TGF-beta signaling pathway increases the activity of the SMAD3/SMAD4 CC transcriptional complex (PubMed:16777850). Interacts (when CC phosphorylated) with RNF111; RNF111 acts as an enhancer of the CC transcriptional responses by mediating ubiquitination and degradation CC of SMAD3 inhibitors (PubMed:9311995). Interacts (dephosphorylated form CC via the MH1 and MH2 domains) with RANBP3 (via its C-terminal R domain); CC the interaction results in the export of dephosphorylated SMAD3 out of CC the nucleus and termination of the TGF-beta signaling CC (PubMed:19289081). Interacts (via MH2 domain) with LEMD3; the CC interaction represses SMAD3 transcriptional activity through preventing CC the formation of the heteromeric complex with SMAD4 and translocation CC to the nucleus (PubMed:15601644, PubMed:15647271). Interacts (via the CC linker region) with EP300 (C-terminal); the interaction promotes SMAD3 CC acetylation and is enhanced by TGF-beta phosphorylation in the C- CC terminal of SMAD3 (PubMed:15588252, PubMed:9843571). This interaction CC can be blocked by competitive binding of adenovirus oncoprotein E1A to CC the same C-terminal site on EP300, which then results in partially CC inhibited SMAD3/SMAD4 transcriptional activity (PubMed:15588252, CC PubMed:9843571).

Also binds zinc CC ions which are necessary for the DNA binding. CC -!- DOMAIN: The MH2 domain is required for both homomeric and heteromeric CC interactions and for transcriptional regulation. Sufficient for nuclear CC import. CC -!- DOMAIN: The linker region is required for the TGFbeta-mediated CC transcriptional activity and acts synergistically with the MH2 domain. CC -!- PTM: Phosphorylated on serine and threonine residues. Enhanced CC phosphorylation in the linker region on Thr-179, Ser-204 and Ser-208 on CC EGF and TGF-beta treatment. Ser-208 is the main site of MAPK-mediated CC phosphorylation. CDK-mediated phosphorylation occurs in a cell-cycle CC dependent manner and inhibits both the transcriptional activity and CC antiproliferative functions of SMAD3. This phosphorylation is inhibited CC by flavopiridol. Maximum phosphorylation at the G(1)/S junction. Also CC phosphorylated on serine residues in the C-terminal SXS motif by TGFBR1 CC and ACVR1. TGFBR1-mediated phosphorylation at these C-terminal sites is CC required for interaction with SMAD4, nuclear location and CC transactivational activity, and appears to be a prerequisite for the CC TGF-beta mediated phosphorylation in the linker region. CC Dephosphorylated in the C-terminal SXS motif by PPM1A. This CC dephosphorylation disrupts the interaction with SMAD4, promotes nuclear CC export and terminates TGF-beta-mediated signaling. Phosphorylation at CC Ser-418 by CSNK1G2/CK1 promotes ligand-dependent ubiquitination and CC subsequent proteasome degradation, thus inhibiting SMAD3-mediated TGF- CC beta responses. Phosphorylated by PDPK1. {ECO:0000269|PubMed:11224571, CC ECO:0000269|PubMed:15241418, ECO:0000269|PubMed:15588252, CC ECO:0000269|PubMed:16156666, ECO:0000269|PubMed:17327236, CC ECO:0000269|PubMed:18794808, ECO:0000269|PubMed:19218245, CC ECO:0000269|PubMed:21947082, ECO:0000269|PubMed:8774881, CC ECO:0000269|PubMed:9843571}.

Monoubiquitinated, leading to prevent DNA-binding CC (PubMed:21947082). Deubiquitination by USP15 alleviates inhibition and CC promotes activation of TGF-beta target genes (PubMed:21947082). CC Ubiquitinated by RNF111, leading to its degradation: only SMAD3 CC proteins that are 'in use' are targeted by RNF111, RNF111 playing a key CC role in activating SMAD3 and regulating its turnover (By similarity).

SMAD3 mutations have been CC reported to be also associated with thoracic aortic aneurysms and CC dissection (TAAD) (PubMed:21778426). This phenotype is distinguised CC from LDS3 by having aneurysms restricted to thoracic aorta. As CC individuals carrying these mutations also exhibit aneurysms of other CC arteries, including abdominal aorta, iliac, and/or intracranial CC arteries (PubMed:21778426), they have been classified as LDS3 by the CC OMIM resource. {ECO:0000269|PubMed:21778426}.
