Signal transduction by transforming growth factor β (TGFβ) coordinates physiological responses in diverse cell types. TGFβ signals via type I and type II receptor serine/threonine kinases and intracellular Smad proteins that regulate transcription. Strength and duration of TGFβ signaling is largely dependent on a negative-feedback program initiated during signal progression. We have identified an inducible gene target of TGFβ/Smad signaling, the salt-inducible kinase (SIK), which negatively regulates signaling together with Smad7. SIK and Smad7 form a complex and cooperate to down-regulate the activated type I receptor ALK5. We further show that both the kinase and ubiquitin-associated domain of SIK are required for proper ALK5 degradation, with ubiquitin functioning to enhance SIK-mediated receptor degradation. Loss of endogenous SIK results in enhanced gene responses of the fibrotic and cytostatic programs of TGFβ. We thus identify in SIK a negative regulator that controls TGFβ receptor turnover and physiological signaling.
