    New England Biolabs treatment with endoh
    HEK293 cells were transfected with Flag-tagged ZMPSTE24 E336A and myc-IFITM3-opsinC (left panels) or Flag-tagged IFITM3 and myc-IFITM3-opsinC (right panels). Proteins were immunoprecipitated with anti-Flag agarose and then mock treated or treated with <t>EndoH</t> or PNGase prior <t>to</t> <t>SDS-PAGE</t> and western blotting. Positions of the glycosylated isoforms of IFITM3-opsinC are indicated. IFITM3-opsinC co-precipitated by ZMPSTE24 E336A was EndoH-and PNGase-sensitive. A glycosylated species of IFITM3-opsinC co-precipitated by Flag-IFITM3 was EndoH-resistant (compare lanes 4 and 5), indicating it had been modified by Golgi-localized glycosyltransferases.

    Incubation:

    Article Title: N-terminal domains and site-specific glycosylation regulate the secretion of avian melanocortin inverse agonists, agouti signaling protein (ASIP) and agouti-related protein (AGRP).
    Article Snippet: Agouti signaling protein (ASIP) and agouti-related protein (AGRP) are paralogous inverse agonists of melanocortin receptors with distinct physiological roles, but their structural and biochemical properties in birds remain poorly understood.. Here, we characterized chicken ASIP and AGRP proteins.. Analysis of available sequences revealed that a motif resembling the mammalian proprotein convertase 1/3 (PC1/3, also known as PCSK1) cleavage site is conserved across a broad range of avian orders, but Western blot analysis of transfected Chinese hamster ovary (CHO-K1) cells and chicken hypothalamus detected no cleavage, suggesting that avian AGRP may not be post-translationally processed at this site.
