Entrez Gene summary for SMAD2 Gene:

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. (provided by RefSeq, May 2012)

GeneCards Summary for SMAD2 Gene:

SMAD2 (SMAD family member 2) is a protein-coding gene. Diseases associated with SMAD2 include colorectal cancer, and ureteral disease. GO annotations related to this gene include transcription factor binding and sequence-specific DNA binding transcription factor activity. An important paralog of this gene is SMAD3.

UniProtKB/Swiss-Prot: SMAD2_HUMAN, Q15796

Function: 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

UniProtKB/Swiss-Prot: SMAD2_HUMAN, Q15796 (See protein sequence)

Recommended Name: Mothers against decapentaplegic homolog 2

Size: 467 amino acids; 52306 Da

Subunit: Momomer; the absence of TGF-beta. Heterodimer; in the presence of TGF-beta. Forms a heterodimer with

co-SMAD, SMAD4, in the nucleus to form the transactivation complex SMAD2/SMAD4. Interacts with AIP1, HGS, PML and

WWP1 (By similarity). Interacts with NEDD4L in response to TGF-beta (By similarity). 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 with SKOR1 and SKOR2. Interacts with PRDM16. Interacts (via MH2 domain) with LEMD3.

Interacts with RBPMS. Interacts with WWP1. 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 ot the TGF-beta signaling. 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

ZNF580

Post-translational modifications:

Phosphorylated on one or several of Thr-220, Ser-245, Ser-250, and Ser-255. In response to TGF-beta,

phosphorylated on Ser-465/467 by TGF-beta and activin type 1 receptor kinases. TGF-beta-induced Ser-465/467

phosphorylation declines progressively in a SETD8-dependent manner. Able to interact with SMURF2 when

phosphorylated on Ser-465/467, recruiting other proteins, such as SNON, for degradation. 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 PDPK1¹

In response to TGF-beta, ubiquitinated by NEDD4L; which promotes its degradation (By similarity).

Monoubiquitinated, leading to prevent DNA-binding. Deubiquitination by USP15 alleviates inhibition and promotes

activation of TGF-beta target genes¹

Acetylated on Lys-19 by coactivators in response to TGF-beta signaling, which increases transcriptional activity.

Isoform short: Acetylation increases DNA binding activity in vitro and enhances its association with target

promoters in vivo. Acetylation in the nucleus by EP300 is enhanced by TGF-beta¹
