The FKBP14 gene provides instructions for making a protein called FKBP prolyl isomerase 14 (also known as FKBP22). This protein is found in a cell structure called the endoplasmic reticulum (ER), which is involved in protein processing and transport. Among its many functions, the endoplasmic reticulum folds and modifies newly formed proteins so they have the 3-dimensional shape they need to function properly. FKBP prolyl isomerase 14 is thought to assist with protein folding, particularly the folding of procollagens. Procollagens are the precursors of collagens, which are complex molecules found in the spaces between cells (the extracellular matrix) that add strength, support, and stretchiness (elasticity) to organs and tissues throughout the body. Studies suggest that FKBP prolyl isomerase 14 may also play a role in processing other components of the extracellular matrix.
