Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD2/SMAD4 complex, activates transcription. May act as a tumor suppressor in colorectal carcinoma. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator (By similarity).By similarity1 Publication

In response to TGF-beta, phosphorylated on the C-terminal SXS motif by TGF-beta and activin type 1 receptor kinases, phosphorylation declines progressively in a KMT5A-dependent manner. Phosphorylation in this motif is required for interaction with a number of proteins including SMURF2, SNON and SMAD4 in response to TGF-beta. Dephosphorylated in this motif by PPM1A leading to disruption of the SMAD2/3-SMAD4 complex, nuclear export and termination of the TGF-beta signaling. In response to decorin, the naturally occurring inhibitor of TGF-beta signaling, phosphorylated on Ser-240 by CaMK2. Phosphorylated by MAPK3 upon EGF stimulation; which increases transcriptional activity and stability, and is blocked by calmodulin. Phosphorylated by PDPK1.3 Publications
In response to TGF-beta, ubiquitinated by NEDD4L; which promotes its degradation. Monoubiquitinated, leading to prevent DNA-binding (PubMed:15496141). Deubiquitination by USP15 alleviates inhibition and promotes activation of TGF-beta target genes (By similarity). Ubiquitinated by RNF111, leading to its degradation: only SMAD2 proteins that are 'in use' are targeted by RNF111, RNF111 playing a key role in activating SMAD2 and regulating its turnover (PubMed:17341133).By similarity2 Publications
Acetylated on Lys-19 by coactivators in response to TGF-beta signaling, which increases transcriptional activity.By similarity

Monomer; the absence of TGF-beta.

Interacts with ZNF580. Heterodimer; in the presence of TGF-beta.

Forms a heterodimer with co-SMAD, SMAD4, in the nucleus to form the transactivation complex SMAD2/SMAD4.

Found in a complex with SMAD3 and TRIM33 upon addition of TGF-beta.

Interacts with ACVR1B, SMAD3 and TRIM33.

Interacts (via the MH2 domain) with ZFYVE9; may form trimers with the SMAD4 co-SMAD.

Interacts with FOXH1, homeobox protein TGIF, PEBP2-alpha subunit, CREB-binding protein (CBP), EP300, SKI and SNW1.

Interacts with SNON; when phosphorylated at Ser-465/467.

Interacts (via PY-motif) with SMURF2.

Interacts with SKOR1 and SKOR2.

Interacts with PRDM16.

Interacts (via MH2 domain) with LEMD3.

Interacts with RBPMS.

Interacts (dephosphorylated form, via the MH1 and MH2 domains) with RANBP3 (via its C-terminal R domain); the interaction results in the export of dephosphorylated SMAD3 out of the nucleus and termination of the TGF-beta signaling.

Interacts with NEDD4L in response to TGF-beta.

Interacts with WWP1, AIP1 and HGS.

Interacts with PML.

Interacts with PDPK1 (via PH domain).

Interacts with DAB2; the interactions are enhanced upon TGF-beta stimulation.

Interacts with USP15.

Interacts with PPP5C.

Interacts with LDLRAD4 (via the SMAD interaction motif).

Interacts (via MH2 domain) with PMEPA1 (via the SMAD interaction motif).

Interacts with ZFHX3 (By similarity).

Interacts with ZNF451.

Identified in a complex that contains at least ZNF451, SMAD2, SMAD3 and SMAD4 (By similarity).

Interacts weakly with ZNF8 (PubMed:12370310).

Interacts (when phosphorylated) with RNF111; RNF111 acts as an enhancer of the transcriptional responses by mediating ubiquitination and degradation of SMAD2 inhibitors (PubMed:17341133).

This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
