In contrast, for proteins putatively annotated to arise from CRC cells (e. g., PSAP, LGALS3BP), the elevation in paucimannosidic glycoforms were generally not accompanied by changes in their protein levels, as exemplified by the site-specific glycoprofiling of a M3F-peptide spanning the Asn69 site of LGALS3BP (Fig. 2G). Here, LGALS3BP is linked to colorectal carcinoma.
