The GLP-1 receptor on RINm5F cells is a glycoprotein with a M(r) of 63,000. Treatment of the receptor with glycopeptidase F generated a protein with a M(r) of 51,000, indicating that the GLP-1 receptor contains N-linked glycans. Tunicamycin pretreatment concentration-dependently decreased GLP-1 binding to RINm5F cells due to a decreased receptor number without change of receptor affinity. Tunicamycin exerted no effect on the GLP-1 receptor mRNA expression. The stimulation of cAMP production was decreased in tunicamycin-treated cells. Our data show that glycosylation of the GLP-1 receptor is a precondition for regular receptor function.
