A housekeeping gene is typically a constitutive gene that is required for the maintenance of basic cellular function, and are expressed in all cells of an organism.[1][2] Although some housekeeping genes are expressed at relatively constant levels (such as HSP90 and Beta-actin), other housekeeping genes may vary depending on experimental conditions.[3] In a recent study involving cardiac stem cells ACTB and GAPDH were found to be the most consistent, while β2M, HPRT-1 and RPLP-1 varied significantly between neonatal and adult cardiac cells.[4][5] The origin of the term "housekeeping gene" remains obscure. Literature from 1976 used the term to describe specifically tRNA and rRNA.[6] Interpreting gene expression data can be problematic, with most human genes registering 5-10 copies per cell (possibly representing error). Housekeeping genes are expressed in at least 25 copies per cell and sometimes number in the thousands.
