| Post Translational Modifications | Contains hydroxylated asparagine residues. Isoform Short N-terminus is blocked. Two intrachain disulfide bonds from the TB3 domain are rearranged upon TGFB1 binding, and form interchain bonds with TGFB1 propeptide, anchoring it to the extracellular matrix. O-glycosylated on serine residues by POGLUT2 and POGLUT3. |
| 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. 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. Outcompeted by LRRC32/GARP for binding to LAP regulatory chain of TGF-beta. |
