Human Anti-SMAD3 scFv-Fc Chimera (VS-0325-FY199) (CAT#: VS-0325-FY199)
This is a recombinant single-chain variable fragments (scFv) fused to the Fc region of human IgG1. It was designed to target different SMAD proteins, key intracellular mediators of the TGF-β signaling pathway. The antibody is specifically validated for use in isPLA, enabling the study of SMAD complex formation and phosphorylation in a cellular context.

Ubiquitinated.
Monoubiquitinated, leading to prevent DNA-binding.
Deubiquitination by USP15 alleviates inhibition and promotes activation of TGF-beta target genes.
Ubiquitinated by RNF111, leading to its degradation: only SMAD3 proteins that are 'in use' are targeted by RNF111, RNF111 playing a key role in activating SMAD3 and regulating its turnover (By similarity).
Undergoes STUB1-mediated ubiquitination and degradation.
Ubiquitination at Lys33 and Lys81
Modification sites at PhosphoSitePlus
Glycosylation from GlyGen 1 site, 1 O-linked glycan (1 site)

- Function
- Human SMAD3 is a signaling protein involved in the TGF-beta signaling pathway, which regulates cell growth, differentiation, and apoptosis. It plays a role in fibrosis and cancer.
