== Function ==
 +
[https://www.uniprot.org/uniprot/FKB1A_HUMAN FKB1A_HUMAN] Keeps in an inactive conformation TGFBR1, the TGF-beta type I serine/threonine kinase receptor, preventing TGF-beta receptor activation in absence of ligand. Recruites SMAD7 to ACVR1B which prevents the association of SMAD2 and SMAD3 with the activin receptor complex, thereby blocking the activin signal. May modulate the RYR1 calcium channel activity. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.<ref>PMID:9233797</ref> <ref>PMID:16720724</ref>

== Publication Abstract from PubMed ==

The structure of the FKBP12-rapamycin-FRB ternary complex has now been refined at 2.2 A resolution. The cell-cycle arrest agent rapamycin binds FK506-binding protein (FKBP12) and the FKBP12-rapamycin binding (FRB) domain of FKBP12-rapamycin associated protein (FRAP) simultaneously, and the inhibition of FRAP is responsible for rapamycin's biological activity. The conformation of rapamycin in the ternary complex is very similar to that observed in the FKBP12-rapamycin binary complex, with an r.m.s. difference of only 0.30 A. However, a slight (9 degrees ) rotation repositions the FRB-binding face of rapamycin in the ternary complex. There are extensive rapamycin-protein interactions and relatively few interactions between the two protein partners FKBP12 and FRB, these interactions mainly involving residues in the 40s and 80s loops of FKBP12 and alpha1 and alpha4 of FRB. The high-resolution refinement has revealed the crucial role of several buried waters in the formation of the ternary complex.
