Description

General description

Collagen type 1 is a fibrillar collagen present abundantly in skin, bone, vasculature, and calcified tissues of teeth and bone. It is also seen in organs like the heart and lungs. Collagen type 1 is a heterotrimer consisting of two α1 (CIα1) and one α2 (CIα2) chains with a helical region made of repeating units of proline and hydroxyproline.

Application

Collagen Type I, Human Skin has been used as a skin protein to study the effect of age-related NADH oxidase (ar-NOX)-catalyzed oxidation on skin proteins. It has also been used as a control sample in High-resolution mass spectrometry (HRMS) analysis.

Biochem/physiol Actions

Collagen type 1 is a main component of the dermal extracellular matrix (ECM) and participates in skin elasticity. Mutations in collagen type 1 are associated with osteogenesis imperfecta and Ehlers–Danlos syndrome.
