Research Backgrounds

Function:

E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Interacts with SMAD1 and SMAD7 in order to trigger their ubiquitination and proteasome-dependent degradation. In addition, interaction with SMAD7 activates autocatalytic degradation, which is prevented by interaction with SCYE1. Forms a stable complex with the TGF-beta receptor-mediated phosphorylated SMAD2 and SMAD3. In this way, SMAD2 may recruit substrates, such as SNON, for ubiquitin-mediated degradation. Enhances the inhibitory activity of SMAD7 and reduces the transcriptional activity of SMAD2. Coexpression of SMURF2 with SMAD1 results in considerable decrease in steady-state level of SMAD1 protein and a smaller decrease of SMAD2 level. Negatively regulates TGFB1-induced epithelial-mesenchymal transition and myofibroblast differentiation.

PTMs:

Auto-ubiquitinated and ubiquitinated in the presence of RNF11 and UBE2D1. Ubiquitinated by the SCF(FBXL15) complex and TTC3, leading to its degradation by the proteasome.

Subcellular Location:

Nucleus. Cytoplasm. Cell membrane. Membrane raft.
Note: Cytoplasmic in the presence of SMAD7. Colocalizes with CAV1, SMAD7 and TGF-beta receptor in membrane rafts.

Tissue Specificity:

Widely expressed.

Subunit Structure:

Interacts (via WW domains) with SMAD1. Interacts (via WW domains) with SMAD2 (via PY-motif). Interacts (via WW domains) with SMAD3 (via PY-motif). Interacts with SMAD6. Interacts with SMAD7 (via PY-motif) and TGFBR1; SMAD7 recruits SMURF2 to the TGF-beta receptor and regulates its degradation. Does not interact with SMAD4; SMAD4 lacks a PY-motif. Interacts with AIMP1. Interacts with STAMBP and RNF11. Interacts with NDFIP1 and NDFIP2 (Probable); this interaction activates the E3 ubiquitin-protein ligase. Interacts with TTC3.

Family&Domains:

The second and third WW domains are responsible for interaction with the PY-motif of R-SMAD (SMAD1, SMAD2 and SMAD3).

The C2 domain is involved in autoinhibition of the catalytic activity by interacting with the HECT domain.

Fig 6 The YBX1/CBX3 axis promotes tumor growth via suppressing SMURF2 in pancreatic cancer. (A-D) PANC-1 and SW1990 cells were transfected with indicated shRNAs for 72 hours. After puromycin selection, cells were harvested for the RT-qPCR (A), MTS (B), and colony formation (C and D). (E-G) PANC-1 cells were transfected with indicated shRNAs for 72 hours. After puromycin selection, cells were subcutaneously injected into the nude mice. The image of tumor was shown in panel E. The tumor mass and tumor growth curve were demonstrated in panel F and G, respectively. Data are presented as mean ± SD (n = 5). (H) PANC-1 and BxPC-3 cells were transfected with indicated shRNAs for 72 hours. After puromycin selection, cells were harvested for the Western blot analysis. (I) PANC-1 and BxPC-3 cells were transfected with indicated shRNAs for 48 hours, and then were transfected with indicated constructs for another 24 hours. Cells were harvested for Western blot. (J) A hypothetic model depicted that CSE exposure-induced YBX1 overexpression contributed to the upregulation of CBX3, which inhibited SMURF2 expression to promote the progression of pancreatic cancer.

Application: WB    Species: Human    Sample: hRGECs

Figure 7 TGF-β2 induces expression of TFPI2 in vitro. Human renal glomerular endothelial cells (hRGECs) were incubated with human recombinant protein TGF-β2 to induce EndMT in vitro. A, the expression of TFPI2 and SMURF2 in hRGECs following treatment of 0, 1, 2.5, 5, or 10 ng/ml TGF-β2 for 48 h. B, the expression of TFPI2 and SMURF2 in hRGECs following treatment of 5 ng/ml TGF-β2 for 0, 12, 24, or 48 h. To explore the molecular mechanism of TGF-β2-induced TFPI2 expression, we next verified whether TFPI2 is a direct target gene of TGF-β/Smad signal. According to JASPAR prediction, TFPI2 is a potential target gene of SMAD2/3/4. C, the promoter activity of TFPI2 gene under TGF-β2 stimulation was detected by Dual-Luciferase Reporter Assay. D, SMAD4 was knocked down in hRGECs in the presence of TGF-β2, which was confirmed by Western blot. E, the expression of TFPI2 was detected in SMAD4-silencing cells. Data are shown as the mean ± SD (n = 3). ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. hRGEC, human renal glomerular endothelial cell; SMURF2, SMAD ubiquitination regulatory factor-2; TFP12, tissue factor pathway inhibitor 2; TGF-β, transforming growth factor beta.
