COMMENT *source: clone=G8123; Three homology regions upstream of the
TATA-box were observed in genes A1, B1 and B2. It may be speculated
that these regions contain signals for the temporally and
regionally controlled activation of the keratin genes during frog
embryogenesis. The transcription of the XK81B1 locus remains unsure
because of no cDNA clone is available. See also X04668 for gene A1
and X05180 for gene B2.
