Post Translational Modifications Phosphorylation of the C-terminal SVS motif by BMP type 1 receptor kinase activates SMAD1 by promoting dissociation from the receptor and trimerization with SMAD4. Phosphorylation by ERK2 MAP kinase in response to EGF or HGF prevents SMAD1 nuclear accumulation and transcriptional activity in response to BMP. Dephosphorylation, probably by PPM1A, induces its export from the nucleus to the cytoplasm. Dephosphorylation is inhibited by association with EGR1. Phosphorylation by CDK8/9 creates binding sites for YAP1, and subsequent phosphorylation by GSK3 switches off YAP1 binding and adds binding sites for SMURF1. Ubiquitinated by SMAD-specific E3 ubiquitin ligase SMURF1, leading to its degradation. Monoubiquitinated, leading to prevent DNA-binding. Deubiquitination by USP15 alleviates inhibition and promotes activation of TGF-beta target genes. Dephosphorylation, probably by PPM1A, induces its export from the nucleus to the cytoplasm. Phospho-SMAD1 is ubiquitinated by CHIP leading to disruption of the SMAD1-SMAD4 complex.
Function Transcriptional modulator that plays a role in various cellular processes, including embryonic development, cell differentiation, and tissue homeostasis. Upon BMP ligand binding to their receptors at the cell surface, is phosphorylated by activated type I BMP receptors (BMPRIs) and associates with SMAD4 to form an heteromeric complex which translocates into the nucleus acting as transcription factor. In turn, the hetero-trimeric complex recognizes cis-regulatory elements containing Smad Binding Elements (SBEs) to modulate the outcome of the signaling network. SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. Positively regulates BMP4-induced expression of odontogenic development regulator MSX1 following IPO7-mediated nuclear import.
