Additional Information Regarding the Antigen
Gene | SMAD2/3 |
Protein | Mothers against decapentaplegic homolog 2/3 |
Uniprot ID | Q15796 |
Function | Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD2/SMAD4 complex, activates transcription. May act as a tumor suppressor in colorectal carcinoma. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator. |
Tissue Specificity | Expressed at high levels in skeletal muscle, endothelial cells, heart and placenta. |
Sub-cellular localization | Cytoplasm. Nucleus. Note: Cytoplasmic and nuclear in the absence of TGF-beta. On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4. On dephosphorylation by phosphatase PPM1A, released from the SMAD2/SMAD4 complex, and exported out of the nucleus by interaction with RANBP1. |
Sequence Similarities | Belongs to the dwarfin/SMAD family. |
