FIG. 1.

Schematic of the primary structure of GAMA. Indicated are the predicted signal peptide (residues 1 to 21) and C-terminal transmembrane domain (residues 715 to 738), the two asparagine-rich regions (residues 38 to 64 and 356 to 485), and the two regions at the N- and C-terminal ends of the protein (NTD, residues 68 to 166; CTD, residues 578 to 714) which were expressed in recombinant form and used to raise specific antisera. The protein consists of 738 amino acids (aa) with a calculated molecular mass of ∼83 kDa.
