cDNA and protein sequence of the NC1 domain of the α2‐chain of collagen IV and its comparison with α1(IV)

Abstract
We present the complete cDNA and derived amino acid sequence of the non-collagenous domain NCl of α2(IV). Comparison with the corresponding NC1 domain of α(IV) reveals a high degree of homology at the protein level in contrast to the barely homologous triple-helical sequences of both chains.
