Figure 1. ORF analysis of Homo sapiens ADA mRNA. Red triangles indicate start codons, green lines indicate stop codons. Black box labels largest ORF in the mRNA sequence. ORF is nucleotides 77-1168. Click here to view the original mRNA sequence.
This ORF codes for a peptide with 364 amino acid residues and a predicted
weight of 40748.26 Daltons.
Figure 2. Ktye-Doolittle Hydrophobicity Plot for Homo sapiens
ADA. There are no points on this plot above the 2.00 threshold, so
no region of the protein is sufficiently hydrophobic to reside in a phospholipid
bilayer. Therefore, ADA is not an integral membrane protein.

ADA. Highly hydrophilic domains likely suitable for use as
antibody epitopes occur near residues 130-140, 310, and 340-350.
