UniProt Comment
  • Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts.

All locus annotations are based on the sentinel SNP (rs35233997).
However, the sentinel SNP is not contained in SNiPA's database (1000 Genomes Project, phase 3 version 5, European population). Thus, no information about linked genes or further functional annotation is available.
