Fibronectin Type III Domain-Containing Protein 4 (FNDC4) — frequently asked
What is FNDC4?
FNDC4 is a fibronectin type III domain-containing protein and the closest relative of FNDC5, the irisin precursor. It is annotated as a membrane protein whose extracellular domain can be shed to produce a soluble circulating form.
How does FNDC4 relate to irisin?
The two proteins share domain architecture, and both are described as releasing a soluble fibronectin type III ectodomain. They are not the same molecule, however, and reported activities and tissue distributions differ, so results should not be assumed to transfer between them.
How well characterised is FNDC4?
Considerably less than FNDC5. A limited number of reports describe anti-inflammatory and metabolic effects and propose GPR116 as a receptor, but independent confirmation is sparse, so findings in this family are best treated as preliminary.
