Genomic fragment including the Met gene, from BAC clone CH321-28O05. A sfGFP-Tag:FLAG-Tag:CS(PSP)-Tag:CS(TEVp)-Tag:BLRP tag cassette has been introduced at the C-terminal end of the Met gene, such that protein isoforms A and B are tagged.
Met-GFP is detected in fat body, salivary gland, prothoracic gland and adult midgut progenitor cells in early wandering third instar larvae but not in the larval midgut cells.
