Background

Function：Transcriptional modulator that plays a role in various cellular processes, including embryonic development, cell differentiation, and tissue homeostasis (PubMed:9335504). 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 a heteromeric complex which translocates into the nucleus acting as transcription factor (PubMed:33667543). In turn, the hetero-trimeric complex recognizes cis-regulatory elements containing Smad Binding Elements (SBEs) to modulate the outcome of the signaling network (PubMed:33667543). 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 (By similarity)

Subcellular Localization：Cytoplasm; Nucleus

Expression：
Tissue_specificity:It is widely distributed. It is expressed most highly in the heart and skeletal muscle.

Isoforms & Post-Translational Modification：Q15797 has 2 isomers: Q15797-1: 52260 Da (predicted); Q15797-2: 15406 Da (predicted).
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 (PubMed:9335504). Dephosphorylation, probably by PPM1A, induces its export from the nucleus to the cytoplasm (By similarity). Dephosphorylation is inhibited by association with EGR1 (By similarity). Phosphorylation by CDK8/9 creates binding sites for YAP1, and subsequent phosphorylation by GSK3 switches off YAP1 binding and adds binding sites for SMURF1 (PubMed:21685363);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 (By similarity). Phospho-SMAD1 is ubiquitinated by CHIP leading to disruption of the SMAD1-SMAD4 complex (PubMed:21454478)

Subunit：Found in a complex with SMAD4 and YY1. Interacts with HGS, NANOG and ZCCHC12 (By similarity). Upon C-terminus phosphorylation: forms trimers with another SMAD1 and the co-SMAD SMAD4 (PubMed:21454478, PubMed:33667543). Interacts with PEBP2-alpha subunit, CREB-binding protein (CBP), p300, SMURF1, SMURF2, USP15 and HOXC8. Associates with ZNF423 or ZNF521 in response to BMP2 leading to activate transcription of BMP target genes. Interacts with SKOR1. Interacts (via MH2 domain) with LEMD3. Binding to LEMD3 results in at least a partial reduction of receptor-mediated phosphorylation. Forms a ternary complex with PSMB4 and OAZ1 before PSMB4 is incorporated into the 20S proteasome. Interacts (via MH2 domain) with FAM83G (via MH2 domain); in a SMAD4-independent manner (PubMed:24554596, PubMed:29789297). Interacts with ZC3H3 (By similarity). Interacts with TMEM119 (By similarity). Interacts (via MH1 and MH2 domains) with ZNF8 (By similarity). Interacts with RANBP3L; the interaction increases when SMAD1 is not phosphorylated and mediates SMAD1 nuclear export (PubMed:25755279). Interacts with EGR1; this interaction inhibits SMAD1 dephosphorylation (By similarity). Interacts with SMAD6 (PubMed:33667543). Interacts with YAP1 (PubMed:21685363). Interacts with MTMR4; negatively regulates BMP signaling through SMAD1 dephosphorylation and retention in endosomes (PubMed:23150675)
