UniProt functional annotation for P68106

UniProt code: P68106.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Has the potential to contribute to the immunosuppressive and toxic effects of FK506 and rapamycin. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
 
Catalytic activity: Reaction=[protein]-peptidylproline (omega=180) = [protein]- peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA- COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833, ChEBI:CHEBI:83834; EC=5.2.1.8;
Activity regulation: Inhibited by both FK506 and rapamycin.
Subunit: Identified in a complex composed of RYR2, FKBP1B, PKA catalytic subunit, PRKAR2A, AKAP6, and the protein phosphatases PP2A and PP1. Interacts directly with RYR2. {ECO:0000269|PubMed:10830164}.
Subcellular location: Cytoplasm {ECO:0000250}. Sarcoplasmic reticulum {ECO:0000250}.
Tissue specificity: Detected in heart muscle (at protein level). Isoform 1 and isoform 2 are ubiquitous with highest levels in brain and thymus. {ECO:0000269|PubMed:10830164}.
Similarity: Belongs to the FKBP-type PPIase family. FKBP1 subfamily. {ECO:0000305}.
