S-x-E sequence motifs in collagens. Locations of S-x-E (or S-x-Sp, whereby the second serine needs to be phosphorylated) motifs recognized by the FAM20C kinase in the collagens are highlighted [1]. The color code used for the sequence pattern S-x-E is red (human), blue (mouse) and black (rat). Reported motifs known to be phosphorylated are marked with a star. Collagen structures are represented as described [61].
