Strongylocentrotus purpuratus Genes in Development
UHF-1
Function
UHF-1 codes for positively acting transcription factor
which is required for high levels of expression of
both EH4 and LH4 genes.
UHF-1 binds more strongly to the EH4 site.
In vivo assays demonstrated that UHF-1 site is required
for maximal EH4 expression, but not for appropriate temporal
regulation (Lee et al., 1991).
