Fig. 1 . Sequence comparison of GLG1 and GLG2. The nucleotide and predicted amino acid sequences of the human monocyte-derived GLG2 are aligned with the published sequence of GLG1 (GenBank accession #NM012201). For convenience, the putative transmembrane and cytoplasmic domains and 3'-UTR of the transcripts for each isoform are shown. The first nucleotide here corresponds to nucleotide #3453 of the registered sequence. The sequences and the direction of the primers used in the present study were also included. The vertical arrow indicates a putative 5'-splicing site. Primers used in the present study were shown by arrows. The amino acid sequence in bold represents the 24-amino-acid extension of GLG2.
