Figure 8  Adam22 gene structure and tissue specific transcripts. (A) RT-PCR analysis. Amplified DNA fragments were analysed by 1 % agarose gel electrophoresis. Lanes 1. 100 bp DNA ladder; 2. cerebellum; 3. spinal cord; 4. dorsal root ganglion; 5. sciatic nerve; 6. cultured Schwann cells; 7. distilled water (B) Exon organization of the mouse Adam22 gene is illustrated. Boxes indicate exons. The G01 transcript (orthologous to the human ADAM22 isoform 1 transcript) is composed of grey boxes. Boxes in black indicate non-coding region. (C) Summary of the isolated clones. The nucleotide sequence data have been deposited with the DDBJ/EMBL/GenBank Data Libraries under the accession numbers described in the table. (D) Number of clones isolated from each tissue is summarized. Cb; cerebellum, Sp; spinal cord, DRG; dorsal root ganglion, SN; sciatic nerve, cSC; cultured Schwann cells.
