ATF6
Encyclopedia
Activating transcription factor 6, also known as ATF6, is a protein
that, in humans, is encoded by the ATF6 gene
and is involved in unfolded protein response
.
(ER) stress-regulated transmembrane transcription factor
that activates the transcription of ER molecules. Accumulation of misfolded proteins in the Endoplasmic Reticulum results in the proteolytic cleavage of ATF6. The cytosolic portion of ATF6 will move to the nucleus and act as a transcription factor to cause the transcription of ER chaperones.

Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

Unfolded protein response
The unfolded protein response is a cellular stress response related to the endoplasmic reticulum. It is a stress response that has been found to be conserved between all mammalian species, as well as yeast and worm organisms...

Interactions
ATF6 has been shown to interactProtein-protein interaction
Protein–protein interactions occur when two or more proteins bind together, often to carry out their biological function. Many of the most important molecular processes in the cell such as DNA replication are carried out by large molecular machines that are built from a large number of protein...
with YY1
YY1
Transcriptional repressor protein YY1 is a protein that in humans is encoded by the YY1 gene.-Interactions:YY1 has been shown to interact with Histone deacetylase 2, FKBP3, ATF6, Myc, SAP30, EP300, HDAC3, NOTCH1 and RYBP....

Serum response factor
Serum response factor , also known as SRF, is a transcription factor.It is a member of the MADS box superfamily of transcription factors. This protein binds to the serum response element in the promoter region of target genes...
