Fibulin-2 is a protein that in humans is encoded by the FBLN2 gene.⁵⁶

This gene encodes an extracellular matrix protein, which belongs to the fibulin family. This protein binds various extracellular ligands and calcium. It may play a role during organ development, in particular, during the differentiation of heart, skeletal and neuronal structures. Alternatively spliced transcript variants encoding different isoforms have been identified.⁶

Its role as a biomarker for meningiomas (a common tumour affecting the central nervous system) was recently described where a blood test can predict whether patients have a grade II meningiomas (poor outcome) and not a grade I meningioma (better outcome), without the need for a surgical biopsy.⁷

Interactions

FBLN2 has been shown to interact with Laminin, alpha 1,⁸⁹ Laminin, alpha 5⁸ and Perlecan.¹⁰¹¹
