The protein–protein interaction network of carp skin mucus proteins. In this network, nodes are proteins, lines represent the predicted functional associations, and the number of lines represents the strength of predicted functional interactions between proteins. Eight proteins including six collagen alpha family proteins (col1a2, col1a1a, col6a1, col6a2, col6a3, col14a1), lumican (lum), and dermatopontin (DPT) were involved in the protein–protein interaction network. The figure shows that collagen type I alpha is the central node of the protein–protein interaction network.
