Abstract

Histone deacetylase (HDAC) removes acetyl group in lysine residue of histone protein, which is transferred by histone acetylase. HDAC is important in the stabilization and regulation of gene expression in eukaryotic organisms. PCR has been carried out to clone HDAC genes using cDNA library and genomic DNA as the templates from Ganoderma lucidum isolated in Korea. One 470 bp cDNA gene fragment, and 3 genomic HDAC fragments (585 bp, 589 bp, 630 bp) were amplified. When their deduced amino acid sequences were compared with other fungal HDACs, they showed 59-72% homology.

염색질을 구성하는 histone 단백질 lysine 잔기에 histone acetylase에 의하여 결합된 acetyl기를 제거하는 histone deacetylase (HDAC)는 진핵세포 생물의 염색질 안정 파 및 유전자 발현에 매우 큰 영향을 미친다. 국내에서 분리된 영지의 HDAC 유전자를 클로닝 하고자 cDNA 및 genomic DNA를 대상으로 PCR을 수행한 결과 470bp의 cDNA유전자와, 585 bp, 589 bp 및 630 bp길이의 genomic DNA유전자 조각을 클로닝 하였다. 이들의 염기서열을 근거로 아미노산 서열을 다른 균류의 HDAC와 비교한 결과 59-72%의 상동성을 보였다.
