InnateDB Gene

IDBG-33239 (FKBP1B)

Protein Structure

UniProt Annotation

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.

Subcellular Localization

Cytoplasm {ECO:0000250}. Sarcoplasmic reticulum {ECO:0000250}.

Disease Associations

Tissue Specificity

Detected in heart muscle (at protein level). Isoform 1 and isoform 2 are ubiquitous with highest levels in brain and thymus. {ECO:0000269PubMed:10830164}.
