Disease relevance of Cyp6a8

  • Heterologous expression of the CYP6A2 protein in lepidopteran cells infected with a Cyp6a2-recombinant baculovirus was observed by Western blotting of cell lysates and by spectral characterization of the reduced-CO complex of the P450 [1].

High impact information on Cyp6a8


Biological context of Cyp6a8

  • These results suggest that -11/-761 Cyp6a8 DNA of the 91-R strain can respond to the active repressor present in the hybrid genome and further support our previous findings that overexpression of Cyp6a8 is a result of mutation of a repressor gene rather than mutation of the cis-regulatory sequences [5].
  • Cyp6a8 has two introns of which intron II is similar to the introns of other insect CYP genes with respect to its length and position [5].
  • Analysis of Cyp6a8 upstream DNA of the overproducer 91-R strain showed that DNA sequences between -199 and -761 bp are required for the highest constitutive and barbital-induced expression of Cyp6a8 [5].
  • In the genome, Cyp6a8 and Cyp6a9 genes are closely clustered within 4 kb and map at region 51C of the second chromosome [4].
  • It is also in-frame with the CYP6A8 open reading frame [5].

Associations of Cyp6a8 with chemical compounds


Other interactions of Cyp6a8

  • In between them another Cyp gene is present which is more related to Cyp6a9 than to Cyp6a8 [4].
