A protein target may have more than one constructs. Every construct has its unique target id.
It can be identified by alias if available, otherwise by local accession with start and end positions. This list of constructs is sorted by stage in desc order.
The start codon is a ATG/Methionine in most of sequences, but the GTG/V, TTG/L, CTG/I can be the start codons in some cases
as expressing in E.coli. The start codon warning is labelled by RED color in sequence(sample: 10174951).
