Identification of human CD40 type II. (A) Gene structure of human CD40. Exons are indicated by boxes. (B)Exon–intron junction sequences are indicated with the nucleotide number of human CD40 cDNA. (C) Structure of human CD40 isoform RNA. Position of alternative splicing and stop codons are indicated by thick solid lines and arrow heads, respectively. Predicted protein structures also are indicated. (D) Partial amino acid sequences of human and mouse CD40 type II are aligned. Type II-specific sequences start from 166 in both. Similarities are indicated by asterisks.
