A constitutive gene is a gene that is transcribed continually as opposed to a facultative gene, which is only transcribed when needed. A housekeeping gene is a gene that is required to maintain basic cellular function and so is typically expressed in all cell types of an organism.

What is NF Y?
NF-Y, also known as the CCAAT-binding factor CBF, is a highly conserved and ubiquitously expressed heterotrimeric transcription factor (TF) composed of the NF-YA, NF-YB, and NF-YC subunits, all three of which are necessary for stable DNA binding of the complex19,20,21,22,23.
What is a nuclear transcription factor?
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. Transcription factors are members of the proteome as well as regulome.
How are constitutive genes regulated?
Some genes are constitutive, or always “on,” regardless of environmental conditions. Such genes are among the most important elements of a cell’s genome, and they control the ability of DNA to replicate, express itself, and repair itself. The repressor or activator protein binds near its regulatory target: the gene.

What is a nuclear transcript?
Nuclear transcription is exerted by three RNA polymerases, RNA polymerase I (Pol I) exclusively dedicated to transcription of ribosomal RNA (exception: 5S rRNA), RNA polymerase II (Pol II) transcribes mRNA and noncoding RNAs, and RNA polymerase III (Pol III) produces tRNAs and 5S rRNA.
What is an inducible gene?
Inducible genes are those that have variable activity, depending on the needs of the cell. For example, the glucose transporter proteins that muscle cells produce in response to insulin are the product of inducible genes. Insulin stimulates their activity. Silenced genes are those that have been permanently turned off.
