NCOA4
Protein-coding gene in the species Homo sapiens
Protein-coding gene in the species Homo sapiens
Nuclear receptor coactivator 4, also known as Androgen Receptor Activator (ARA70), is a protein that in humans is encoded by the NCOA4 gene. It plays an important role in ferritinophagy, acting as a cargo receptor, binding to the ferritin heavy chain and latching on to ATG8 on the surface of the autophagosome.
Interactions
NCOA4 has been shown to interact with:
- Androgen receptor, and
- Peroxisome proliferator-activated receptor gamma
- Ferritin
- ATG8
