Schematic of glycoforms and proteolytic fragments of UniProtKB/SwissProt entry Q14624.
A, full-length protein with signal peptide, domains (labeled), N-glycosylation sites (black circles), and proposed O-glycosylation sites (white circles); B, cleavage of mature protein by plasma kallikrein; C, additional internal cleavage of protein fragments. Asterisks indicate proteolytic fragments (frag.) detected in serum.
