About FKBP1B

Cytogenetic location: 2p23.3 Genomic coordinates (GRCh38): 2:24,033,206-24,063,681 (from NCBI)

This gene has 6 transcripts (splice variants), 188 orthologues and 18 paralogues. Ubiquitous expression in duodenum (RPKM 4.2), brain (RPKM 2.6) and 25 other tissues.

Summary

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. This encoded protein is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. It is highly similar to the FK506-binding protein 1A. Its physiological role is thought to be in excitation-contraction coupling in cardiac muscle. There are two alternatively spliced transcript variants of this gene encoding different isoforms.
