CC   -!- FUNCTION: Non-functional truncated transcription activator.
CC       {ECO:0000269|PubMed:20949001}.
CC   -!- MISCELLANEOUS: Corresponds to one of the seven genes studied by Gregor
CC       Mendel in 1866. The wild type purple flowers (A allele) have a
CC       functional BHLH protein (AC E3SXU4) (PubMed:20949001).
CC       {ECO:0000305|PubMed:20949001}.
CC   -!- SIMILARITY: Belongs to the bHLH protein family.
