The tissue form of chicken type VI collagen.
We have purified intact type VI collagen from chicken gizzard. The protein was found to consist of a 130 kDa, a 140 kDa and a 180-200 kDa subunit. The 130 kDa and 140 kDa subunits were obtained in equimolar amounts and identified as the alpha 2 (VI) and the alpha 1 (VI) chains, respectively. The third subunit was usually obtained in the form of 3-4 closely related polypeptides, which may represent different processing or modification products of the alpha 3 (VI) chain.
