The O-fucosylation of proteins containing thrombospondin type 1 repeat (TSR1) domains is carried out by protein fucosyltransferase 2 (POFUT2). Only POFUT2 recognises the consensus sequence CSXS/TCG found in TSR1 domains and the fucosyl residue is attached to the hydroxyl group of conserved serine (S) or threonine (T) residues within the consensus sequence (Chen et al. 2012). The modification was first demonstrated on thrombospondin 1 (THBS1, TSP1), found in platelets and the ECM (Hofsteenge et al. 2001, Luo et al. 2006). In humans, there are more than 60 of these TSR1 domain-containing proteins. Only the proteins with similarity to experimentally confirmed ones are listed as candidates.
