Based on limited published evidence, FKBP1C is a peptidyl-prolyl cis-trans isomerase that catalyzes proline isomerization in oligopeptides and facilitates protein folding. UniProt annotations indicate involvement in regulating cardiac muscle contraction through sarcoplasmic reticulum calcium release. A whole-exome sequencing study of Nigerian benign prostatic hyperplasia samples identified FKBP1C somatic variants at significantly elevated frequency, suggesting potential involvement in apoptotic pathway dysfunction 1. However, functional validation of these associations remains limited.
