摘要:
The invention is directed to methods for optimizing glycan processing in organisms (and in particular, plants) so that a glycoprotein having complex type bi-antennary glycans and thus containing galactose residues on both arms and which are devoid of (or reduce in) xylose and fucose can be obtained. The invention is further directed to said glycoprotein obtained and host system comprising said protein.
摘要:
The present invention relates to a method to produce proteins reduced in high mannose type glycans in a plant or plant cell by partially inhibiting the expression of the Alg3 gene in said plant or plant cell. Said partial inhibition can be provided for by inserting the Alg3 mutant gene from Arabidopsis as derived from the plant line Salk_040296c or by partially inhibiting the endogenous Alg3 gene by providing the plant or plant cell either with an antisense expression, a sense co-suppressing or with an RNA inhibition genetic construct. Optionally also tissue-specific expression of said inhibiting constructs can yield partial inhibition in a plant.
摘要:
The invention relates to a protein complex for the delivery of an antigen to and across mucosal surfaces and the production of said complex in a host cell, such as a plant. Provided is a protein complex comprising at least two, preferably identical, subunits wherein at least one subunit is unaltered and at least one subunit is fused to a first molecule of interest and wherein the protein complex is able to interact with a cell surface receptor via said subunits. Also provided is a method for producing a protein complex according to the invention, comprising a) providing a host cell with a nucleotide sequence encoding an unaltered subunit and a nucleotide sequence encoding a molecule of interest, wherein at least one molecule of interest is fused to a subunit; b) culturing said host cell thereby allowing expression of said nucleotide sequences and allowing for assembly of the protein complex; c) isolating the complex; d) determining the binding of the complex to a cell surface receptor or to a molecule which mimics a cell surface receptor
