Genomic sequence

Coding region sequence

The coding region (CODING-REGION) sequence starts from INIT-CODON (or its encoded amino acid) to STOP-CODON (not included).
The nucleotide sequence is extracted from cDNA (c) sequences and/or is built by artificial exon joining from genomic DNA (g) sequences. The amino acid sequence is the translation of the nucleotide sequence.
