Repetitive sequence environment distinguishes housekeeping genes.
Housekeeping genes are expressed across a wide variety of tissues. Since repetitive sequences have been reported to influence the expression of individual genes, we employed a novel approach to determine whether housekeeping genes can be distinguished from tissue-specific genes by their repetitive sequence context. We show that Alu elements are more highly concentrated around housekeeping genes...
متن کاملDo Housekeeping Genes Exist?
The searching of human housekeeping (HK) genes has been a long quest since the emergence of transcriptomics, and is instrumental for us to understand the structure of genome and the fundamentals of biological processes. The resolved genes are frequently used in evolution studies and as normalization standards in quantitative gene-expression analysis. Within the past 20 years, more than a dozen ...

متن کاملPredicting Housekeeping Genes Based on Fourier Analysis
Housekeeping genes (HKGs) generally have fundamental functions in basic biochemical processes in organisms, and usually have relatively steady expression levels across various tissues. They play an important role in the normalization of microarray technology. Using Fourier analysis we transformed gene expression time-series from a Hela cell cycle gene expression dataset into Fourier spectra, an...
متن کاملOn the nature of human housekeeping genes.
Using a collection of expressed sequence tag (EST) data, we re-evaluated the correlation of tissue specificity with genomic structure, phyletic age, evolutionary rate and promoter architecture of human genes. We found that housekeeping genes are less compact and older than tissue-specific genes, and they evolve more slowly in terms of both coding and core promoter sequences. Housekeeping genes ...
