Smad1 (Phospho Ser214) rabbit pAb

Function:Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD) ., PTM:Phosphorylated on serine by BMP type 1 receptor kinase., PTM:Ubiquitin-mediated proteolysis by SMAD-specific E3 ubiquitin ligase SMURF1., similarity:Belongs to the dwarfin/SMAD family., similarity:Contains 1 MH1 (MAD homology 1) domain., similarity:Contains 1 MH2 (MAD homology 2) domain., subcellular location:Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4., subunit:Interacts with HGS, NANOG and ZCCHC12 (By similarity) . May form trimers with another SMAD1 and the co-SMAD SMAD4. Interacts with PEBP2-alpha subunit, CREB-binding protein (CBP), p300, SMURF1, SMURF2 and HOXC8. Associates with ZNF423 or ZNF521 in response to BMP2 leading to activate transcription of BMP target genes. Interacts with LBXCOR1., tissue specificity:Ubiquitous. Highest expression seen in the heart and skeletal muscle.
