5GGATG3

5GGATG3 is a fictional gene designation commonly used in educational datasets and bioinformatics tutorials to illustrate gene annotation conventions. The label combines a 5' end motif indicator with a short sequence fragment (GGATG) and a trailing numeric index, which in practice helps learners distinguish among multiple exemplar entries in a database.

Purpose and scope: As a didactic construct, 5GGATG3 does not correspond to a verified gene or locus in an experimentally characterized organism. In example files, it is used to demonstrate features such as transcript annotation, open reading frames, coding sequences, and basic gene model structure without implying real biological function.

Representation: In a typical educational dataset, 5GGATG3 would be defined with a fictional genomic coordinates, strand, and transcript variants. If used as a coding sequence in exercises, learners may assume a hypothetical start codon, reading frame, and stop codon, but no actual expression data exists.

Relevance: The concept underscores standard annotation practices, including the importance of unique identifiers, sequence context, and metadata for reproducibility. It is also used to illustrate common pitfalls, such as overfitting annotations to short motifs.
