Background
-
Function
Smad1 is a BMP-responsive receptor-regulated Smad whose phosphorylation is rapidly induced by BMP2, driving nuclear accumulation and BMP signal transduction[1]. Mechanistically, BMP receptors phosphorylate Smad1, Smad1 associates with Smad4, and the complex enters the nucleus to activate transcription[2]. In BMP-responsive promoters such as ID1, Smad1/Smad4-dependent DNA binding supports BMP-specific transcriptional activation[3]. In developmental models, canonical Smad1/5 signaling is required for endochondral bone formation, and SMAD1/5 activity controls spinal neural progenitor division modes[4][5]. In disease-relevant models, BMP-Smad1 signaling participates in DNA damage response and oncogenesis through the Atm-p53 pathway[6]. Compared with related BMP-regulated isoforms, Smad9 shows lower transcriptional activity than Smad1 or Smad5 despite Smad4 association and target-DNA binding, distinguishing Smad1 as a stronger BMP transcriptional effector[7]. For experimental applications, Smad6 blocks BMP/Smad1 signaling by competing with Smad4, while dorsomorphin and LDN-193189 inhibit BMP-mediated Smad signaling in C2C12 cells[2][8].

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)
