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).

- Sequence similarities
Belongs to the dwarfin/SMAD family.
- 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 (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).

- Activity summary
Smad1 also known as Mothers against decapentaplegic homolog 1 (MADH1) is a protein encoded by the SMAD1 gene in humans. It has a molecular mass of approximately 53 kDa and functions as a receptor-regulated Smad protein. Smad1 primarily transmits signals from the bone morphogenetic proteins (BMPs) a group of growth factors and cytokines. Expression of Smad1 occurs in various tissues including the lung heart and kidney. It plays an important role in mediating signaling pathways within different cellular environments.
- Biological function summary
Smad1 participates in the transmission of BMP signals from the cell surface to the nucleus ensuring transcriptional regulation of target genes. In the presence of BMPs Smad1 forms complexes with Smad4 upon activation. These Smad complexes then translocate to the nucleus where they regulate gene expression. Smad1 influences cellular responses such as proliferation differentiation and apoptosis. In particular it plays a significant role in bone development and osteogenesis.
- Pathways
Smad1 plays an important role within the BMP signaling pathway which is important for early development and tissue homeostasis. Within this pathway BMPs trigger the phosphorylation of Smad1 which then associates with Smad4 to propagate downstream signaling. Another associated pathway includes the TGF-beta signaling pathway where Smads like Smad2 and Smad3 show functional similarities and differences with Smad1. The interactions of Smad1 with related proteins like Smad4 highlight its significant contribution to cellular processes regulated by these pathways.
- Associated diseases and disorders
Smad1 associates with various pathological conditions. For instance aberrant Smad1 signaling has implications in cancer particularly in processes like tumor progression and metastasis. Disruptions in the BMP pathway involving Smad1 and Smad4 can influence the onset and development of disorders such as pulmonary hypertension where inappropriate cell growth and remodeling occur. Understanding Smad1's role in these contexts provides insights into potential therapeutic avenues for treatment and management of these conditions.
