Organism

Organism UniProt Comment Textmining
Phaeodactylum tricornutum B7FQV6 Phaeodactylum tricornutum genome contains three copys of ZEP. As compared to the plant ZEPs, the amino acid region covering lipocalin motif I is considerably larger in the diatom ZEP1 and ZEP2 proteins, but not in PtZEP3 and the motif I consensus sequence is not conserved in any of the diatom ZEPs

Phaeodactylum tricornutum B7FUR7 Phaeodactylum tricornutum genome contains three copys of ZEP. As compared to the plant ZEPs, the amino acid region covering lipocalin motif I is considerably larger in the diatom ZEP1 and ZEP2 proteins, but not in PtZEP3 and the motif I consensus sequence is not conserved in any of the diatom ZEPs

Expression

Organism Comment Expression
Phaeodactylum tricornutum white and blue light increase mRNA levels of ZEP1, ZEP2 and ZEP3 1 to 8 hours after lights on, red light slightly upregulates transcription of ZEP2 gene, but has no effect on ZEP1 and ZEP3 up
