WebPin1 Protein Overview. Peptidyl-prolyl cis/trans isomerases (PPIases; EC 5.2.1.8), such as PIN1, catalyze the cis/trans isomerization of peptidyl-prolyl peptide bonds. PIN1 is the only PPIase that specifically binds to phosphorylated ser/thr-pro motifs to catalytically regulate the post-phosphorylation conformation of its substrates. WebPin1 also enhances the dephosphorylation of substrates by protein phosphatases, all of which requires the pSer–Pro bond to be in trans. Because the WW domain can only bind … WebAug 29, 2024 · Pin1 is comprised of an N-terminal WW domain and a C-terminal PPIase domain, which are connected by a flexible linker 11,12.
