V-myc myelocytomatosis viral related oncogene, neuroblastoma derived (avian), also known as MYCN, is a protein which in humans is encoded by the MYCN gene.

Function

This gene is a member of the MYC family of transcription factors and encodes a protein with a basic helix-loop-helix (bHLH) domain. This protein is located in the nucleus and must dimerize with another bHLH protein in order to bind DNA.

Clinical significance

Amplification of this gene is associated with a variety of tumors, most notably neuroblastomas.

Interactions

N-Myc has been shown to interact with MAX.

N-Myc is also stabilized by Aurora A which protects it from degradation.
