Detection of Human/Mouse/Rat Fibromodulin by Western Blot. Western blot shows lysates of human cartilage, human ovarian cancer, and rat uterine tissue. PVDF membrane was probed with 0.3 µg/mL of Sheep Anti-Human/Mouse/Rat Fibromodulin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5945) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Fibromodulin at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Fibromodulin (FMOD; also FM and collagen-binding 59 kDa protein) is a secreted, 60‑70 kDa class II member of the SLRP family of matrix proteins. It is expressed by a variety of cell types, including keratinocytes, fibroblasts and chrondrocytes, and is known to bind to type I and XII collagen, plus TGF-beta. Fibromodulin is posited to displace lumican binding to collagen, generating 3D collagen fibrils from simple lumican-induced collagen dimers. Mature human Fibromodulin is 358 amino acids (aa) in length (aa 19‑376). It contains 12 LRRs (Leu-rich repeats) (aa 98‑376), with the seventh and eleventh LRR principally responsible for collagen type I binding. Fibromodulin contains varying amounts of keratan sulfate, and undergoes significant tyrosine sulfation. There is one splice form that shows a deletion of aa 88‑101. Over aa 76‑376, human Fibromodulin shares 96% aa identity with mouse and rat Fibromodulin.
