Recombinant Human Peptidyl-prolyl cis-trans isomerase FKBP1A (FKBP1A), Truncated

Uniprot Id

P62942

Target Species

Human

Target Name

FKBP1A

Target Full Name

Peptidyl-prolyl cis-trans isomerase FKBP1A

Target Function

Keeps in an inactive conformation TGFBR1, the TGF-beta type I serine/threonine kinase receptor, preventing TGF-beta receptor activation in absence of ligand. Recruits 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.

Target Subcellular Location

Cytoplasm, cytosol. Sarcoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side.

Target Protein Families

FKBP-type PPIase family, FKBP1 subfamily

Target Background

The protein encoded by this gene is a member of the immunophilin protein family, which play a role in immunoregulation and basic cellular processes involving protein folding and trafficking. The protein is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. It interacts with several intracellular signal transduction proteins including type I TGF-beta receptor. It also interacts with multiple intracellular calcium release channels, and coordinates multi-protein complex formation of the tetrameric skeletal muscle ryanodine receptor. In mouse, deletion of this homologous gene causes congenital heart disorder known as noncompaction of left ventricular myocardium. Multiple alternatively spliced variants, encoding the same protein, have been identified. The human genome contains five pseudogenes related to this gene, at least one of which is transcribed.
