Housekeeping genes are genes that are expressed in virtually every cell in your body because they encode proteins required for all cells to function. For example, actin and RNA polymerase are housekeeping genes. Housekeeping genes are typically found in euchromatin, which is a type of chromatin that is less condensed and more accessible to transcription factors. This allows housekeeping genes to be transcribed and expressed at a relatively constant rate in all cells.

Euchromatin is characterized by a number of features, including:

• It is less condensed than heterochromatin.
• It is more accessible to transcription factors.
• It has a higher proportion of active genes.
• It is enriched in histone modifications that promote gene expression.

Housekeeping genes are essential for the survival of all cells, so it is important that they are expressed in a reliable and consistent manner. Euchromatin provides the ideal environment for the expression of housekeeping genes.

Here are some examples of housekeeping genes:

• Actin
• RNA polymerase
• Glyceraldehyde 3-phosphate dehydrogenase (GAPDH)
• Hypoxanthine phosphoribosyltransferase (HPRT1)
• Ribosomal protein L10 (RPLP0)

These genes encode proteins that are involved in a variety of essential cellular processes, such as metabolism, gene expression, and protein synthesis.

Housekeeping genes are important for maintaining normal cellular function. They are also important for understanding the molecular basis of disease. By studying the expression of housekeeping genes, researchers can gain insights into the mechanisms of disease and develop new treatments.
