Expressed at high levels in skeletal muscle, endothelial cells, heart and placenta.

描述:
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.

研究背景

功能:

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.

翻译修饰:

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 KMT5A-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 PDPK1.

In response to TGF-beta, ubiquitinated by NEDD4L; which promotes its degradation. Monoubiquitinated, leading to prevent DNA-binding (By similarity). Deubiquitination by USP15 alleviates inhibition and promotes activation of TGF-beta target genes. 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 (By similarity).

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-beta.

细胞定位:

Cytoplasm. Nucleus.
Note: Cytoplasmic and nuclear in the absence of TGF-beta. On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4 (PubMed:9865696). On dephosphorylation by phosphatase PPM1A, released from the SMAD2/SMAD4 complex, and exported out of the nucleus by interaction with RANBP1 (PubMed:16751101, PubMed:19289081).

组织特异性:

Expressed at high levels in skeletal muscle, endothelial cells, heart and placenta.

亚基结构:

Monomer; 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 of 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. Interacts with LDLRAD4 (via the SMAD interaction motif). Interacts (via MH2 domain) with PMEPA1 (via the SMAD interaction motif). Interacts with ZFHX3. Interacts with ZNF451. Identified in a complex that contains at least ZNF451, SMAD2, SMAD3 and SMAD4. Interacts weakly with ZNF8 (By similarity). Interacts (when phosphorylated) with RNF111; RNF111 acts as an enhancer of the transcriptional responses by mediating ubiquitination and degradation of SMAD2 inhibitors (By similarity).
