Clone RB04101
Isotype Ig
Predicted Reactivity Xenopus laevis,Zebrafish
Purification This antibody is prepared by Saturated Ammonium Sulfate (SAS) precipitation followed by dialysis against PBS.
Alternative Name SMURF1
Background Members of the transforming growth factor-beta (TGFB) family signal through type I and type II serine/threonine-kinase receptors, which in turn activate the SMAD signaling pathway. Bone morphogenetic protein (BMP) receptors target SMAD1, SMAD5, and SMAD8, whereas receptors for activin and TGFB (e.g., ACVR1 and TGFBR1, respectively) target SMAD2 and SMAD3. Phosphorylation of these receptor-regulated SMADs induces their association with the common-partner SMAD, SMAD4. Smurf1, a HECT domain E3 ubiquitin ligase, regulates cell polarity and protrusive activity and is required to maintain the transformed morphology and motility of a tumor cell. Atypical protein kinase C-zeta (PKC2), an effector of the Cdc42/Rac1-PAR6 polarity complex, recruits Smurf1 to cellular protrusions, where it controlled the local level of RhoA. Smurf1 thus links the polarity complex to degradation of RhoA in lamellipodia and filopodia to prevent RhoA signaling during dynamic membrane movements.

Application Notes Suggested dilutions:
WB = 1:1000, IHC = 1:10-50
Optimal working dilution should be determined by the investigator.
Restrictions For Research Use only
Format Liquid
Concentration 2 mg/mL
Buffer PBS with 0.09 % (W/V) sodium azide
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Avoid freeze-thaw cycles.
Storage 4 °C/-20 °C
Storage Comment Maintain refrigerated at 2-8 °C for up to 6 months. For long term storage store at -20 °C in small aliquots.
Expiry Date 6 months

anti-SMAD Specific E3 Ubiquitin Protein Ligase 1 (SMURF1) (N-Term), (AA 66-96) antibody Western blot analysis of anti-SMURF1 Pab (ABIN388828) in mouse kidney tissue lysate (35 µg/lane). SMURF1(arrow) was detected using the purified polyclonal antibody.
anti-SMAD Specific E3 Ubiquitin Protein Ligase 1 (SMURF1) (N-Term), (AA 66-96) antibody (2) C2C12 or 2T3 cells were treated with PBS or TNF (2.5-7.5 ng/mL) for 72 h. Smurf1 and actin protein levels were detected by Western blot (ABIN388828 Smurf1 N-term antibody).
anti-SMAD Specific E3 Ubiquitin Protein Ligase 1 (SMURF1) (N-Term), (AA 66-96) antibody (3) Proteins were extracted from the metaphyseal region of 4-month-old TNF-over-expressing mice (TNF-Tg) and wild type (wt) littermates (left panel). PBS or TNF was injected (0.25 ug/injection, 3 times/day for 3 days) into the calvarial bones of wt mice. Proteins were extracted from the bones and analyzed by Western blotting for Smurf1 (ABIN388828 Smurf1 N-term antibody), Runx2 and alpha-actin protein levels (right panel).
