What pLDDT means and how to read it

Function

Key regulator of transforming growth factor beta (TGFB1, TGFB2 and TGFB3) that controls TGF-beta activation by maintaining it in a latent state during storage in extracellular space (PubMed:19651619, PubMed:19750484, PubMed:22278742). Associates specifically via disulfide bonds with the Latency-associated peptide (LAP), which is the regulatory chain of TGF-beta, and regulates integrin-dependent activation of TGF-beta (PubMed:22278742). Able to outcompete LTBP1 for binding to LAP regulatory chain of TGF-beta (PubMed:22278742). Controls activation of TGF-beta-1 (TGFB1) on the surface of activated regulatory T-cells (Tregs) (PubMed:19651619, PubMed:19750484). Required for epithelial fusion…

Subunit structure

Interacts with TGFB1; associates via disulfide bonds with the Latency-associated peptide chain (LAP) regulatory chain of TGFB1, leading to regulate activation of TGF-beta-1 (PubMed:19651619, PubMed:22278742). Interacts with TGFB2 (PubMed:19651619). Interacts with TGFB3; associates via disulfide bonds with the Latency-associated peptide chain (LAP) regulatory chain of TGFB3, leading to regulate…
