Housekeeping Genes. The numbers of housekeeping genes and tissuespecific genes Download Table Author summary Housekeeping genes have often been associated with four main biological criteria-stability in expression across samples, essentiality, participation in cellular maintenance, and evolutionarily conserved Biochemical studies on transcription initiation of the housekeeping gene promoters have been difficult, partly due to the less-characterized promoter motifs.

Housekeeping genes are of broad interest for translational and basic science research Housekeeping genes are commonly described as "essential for cellular existence regardless of their specific function in the tissue or organism", and.
Godbey, in An Introduction to Biotechnology, 2014 4.2.3.2.1.2 CpG Islands The TATA box is not the only feature that can be used to identify the location of the gene Thus, they are expected to be expressed in all cells of an organism under normal conditions, irrespective of tissue type, developmental stage, cell cycle state, or external signal Some genes, however, are constitutively expressed in all tissues and their expression levels are comparatively constant across different cell types
(PDF) Do 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 For instance, there is a class of genes that is constantly being expressed, known as housekeeping genes
