additional information
-
A conserved AP-1 (JNK activated transcription factor complex) binding upstream of the DDC transcription start site is necessary to induce DDC transcription
-
additional information
-
aseptic wounding of larvae or adults does not lead to DDC transcriptional induction, unlike in embryos where DDC activity at the edge of the wound contributes to the formation of a melanin clot
-
additional information
-
Transcription of the dopa decarboxylase gene is induced in response to gram-negative and gram-positive septic injury, but not aseptic wounding. Ddc transcripts are detectible within 2 h and remain high for several hours following infection with either gram-negative (Escherichia coli) or gram-positive (Staphylococcus aureus) bacteria. Ddc transcription depends on a previously uncharacterized member of the p38 mitogen-activated protein kinase family, p38c
