Target Information
Members of the transforming growth factor-beta (TGFB) family signal through type I and type II serine/threonine-kinase receptors, activating the SMAD signaling pathway. Bone morphogenetic protein (BMP) receptors target SMAD1, SMAD5, and SMAD8, while activin and TGFB receptors (e.g., ACVR1 and TGFBR1) target SMAD2 and SMAD3. Phosphorylation of these receptor-regulated SMADs induces association with SMAD4.
Smurf1, a HECT domain E3 ubiquitin ligase, regulates cell polarity and protrusive activity, maintaining the transformed morphology and motility of tumor cells. Atypical protein kinase C-zeta (PKCζ), an effector of the Cdc42/Rac1-PAR6 polarity complex, recruits Smurf1 to cellular protrusions, controlling local RhoA levels. Smurf1 thus links the polarity complex to RhoA degradation in lamellipodia and filopodia, preventing RhoA signaling during dynamic membrane movements.
