SMURF1, NT (SMURF1, KIAA1625, E3 ubiquitin-protein ligase SMURF1, SMAD ubiquitination regulatory factor 1, SMAD-specific E3 ubiquitin-protein ligase 1) (Azide free) (HRP)

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.\n\nApplications:\nSuitable for use in Western Blot, Immunohistochemistry, ELISA\n\nRecommended Dilution:\nELISA: 1:1,000\nWestern Blot: 1:100-500\nImmunohistochemistry: 1:50-100\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Do not freeze horseradish peroxidase conjugates which could result in a substantial loss of enzymatic activity. Light sensitive. Aliquots are stable for 6 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
