Cloning and characterisation of a procorticotrophin-releasing hormone in the IZD-MB-0503 immunocyte line from the insect Mamestra brassicae.
The cloning and characterisation of a procorticotrophin-releasing hormone (proCRH) and the related CRH fragment in the IZD-MB-0503 cell line from the leptidopteran Mamestra brassicae were performed. PCR amplification of the genomic DNA reveals a fragment of 276 bp, while inverse PCR shows the presence of a gene consisting of 1153 bp. The comparison of the insect genomic proCRH gene with proCRH cDNA obtained by RACE shows the presence of three introns. There was a 61% identity with the corresponding coding sequence in Tilapia mossambica, and a 65.2% identity with the human proCRH coding sequence.
