FKBP14 also known as FK506-binding protein 14 is a member of the FKBP family of proteins. It acts as a peptidyl-prolyl cis-trans isomerase assisting in the folding of certain proteins by accelerating the interconversion between proline residues. FKBP14 displays a molecular mass of approximately 23 kDa and is expressed in various tissues throughout the body including muscle and connective tissues. The protein typically resides in the endoplasmic reticulum where its main role involves assisting in protein folding processes ensuring proper cellular function.

Biological function summary

FK506-binding protein 14 impacts protein assembly and stabilization. It participates in the modification and folding of newly synthesized proteins particularly collagens which are essential for maintaining structural integrity in tissues. FKBP14 does not operate as part of a larger complex but plays a significant role in maintaining the stability and functionality of extracellular matrix components. This activity highlights its importance in tissue homeostasis and cellular maintenance.

Pathways

FKBP14 is integral to collagen biosynthesis and quality control pathways contributing to the structural framework of tissues. It influences the proper secretion and assembly of collagen types interacting with proteins like collagen type I through these processes. These pathways are critical for maintaining the extracellular matrix's structural properties ensuring that tissues correctly support cellular activities and organ architecture.

FKBP14 mutations or dysregulation connect to conditions like Bruck syndrome and Ehlers-Danlos syndrome. These diseases involve connective tissue abnormalities where defective collagen processing leads to impaired tissue integrity. Within Bruck syndrome FKBP14 directly relates to incorrect collagen modification which affects structural strength associating with proteins such as lysyl hydroxylase. Studying the interactions and functions of FKBP14 provides insight into these connective tissue disorders' underlying mechanisms and potential therapeutic targets.
