Background Information Members of the Smad family of signal transduction molecules are components of a critical intracellular pathway that transmits TGF-β signals from the cell surface into the nucleus. Three distinct classes of Smads have been defined: the receptor-regulated Smads (R-Smads), which include Smad1, 2, 3, 5 and 8, the common-mediator Smad (co-Smad), Smad4, and the antagonistic or inhibitory Smads (I-Smads), Smad6 and 7. Once in the nucleus, Smads can target a variety of DNA binding proteins to regulate transcriptional responses. Following stimulation by TGF-β, Smad2 and Smad3 become phosphorylated at their carboxyl termini (Ser465 and 467 on Smad2; Ser423 and 425 on Smad3) by TGF-β Receptor I. Phosphorylated Smad 2/3 can complex with Smad4, translocate to the nucleus and regulate gene expression.

UniProt Number
UniProt Summary FUNCTION: Transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinase. SMAD3 is a receptor-regulated SMAD (R-SMAD) By similarity.

SUBUNIT STRUCTURE: Interacts with HGS. Interacts with NEDD4L in response to TGF-beta. Interacts with TTRAP By similarity. Interacts with SARA (SMAD anchor for receptor activation); form trimers with another SMAD3 and the co-SMAD SMAD4. Interacts with JUN/FOS, vitamin D receptor, homeobox protein TGIF and TGIF2, PEBP2-alpha C subunit, CREB-binding protein (CBP), p300, SKI, SNON, ATF2, SMURF2, AIP1, DACH1 and TGFB1I1. Part of a complex consisting of AIP1, ACVR2A, ACVR1B and SMAD3. Found in a complex with SMAD2 and TRIM33 upon addition of TGF-beta. Interacts with SMAD2 and TRIM33. Found in a complex with SMAD3, Ran and XPO4. Interacts with XPO4. Interacts with LBXCOR1 and CORL2.

SUBCELLULAR LOCATION: CytoplasmBy similarity. NucleusBy similarity. Note= In the cytoplasm in the absence of ligand. Migration to the nucleus when complexed with SMAD4 By similarity.

DOMAIN: The MH2 domain is sufficient to carry protein nuclear export.

PTM: Phosphorylated on serine by TGF-beta and activin type 1 receptor kinases.

INVOLVEMENT IN DISEASE: Defects in SMAD3 may be a cause of colorectal cancer (CRC) [MIM:114500].

SEQUENCE SIMILARITIES: Belongs to the dwarfin/SMAD family.

Contains 1 MH1 (MAD homology 1) domain.

Contains 1 MH2 (MAD homology 2) domain.
