CC   -!- FUNCTION: Involved in protein export. Acts as a chaperone by
CC       maintaining the newly synthesized protein in an open conformation.
CC       Functions as a peptidyl-prolyl cis-trans isomerase (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC         peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-
CC         COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833,
CC         ChEBI:CHEBI:83834; EC=5.2.1.8;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Note=About half TF is bound to the
CC       ribosome near the polypeptide exit tunnel while the other half is free
CC       in the cytoplasm. {ECO:0000250}.
CC   -!- DOMAIN: Consists of 3 domains; the N-terminus binds the ribosome, the
CC       middle domain has PPIase activity, while the C-terminus has intrinsic
CC       chaperone activity on its own. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FKBP-type PPIase family. Tig subfamily.
CC       {ECO:0000305}.
