Jun Proto-Oncogene (C-JUN) Human Active Protein

This gene is the putative transforming gene of avian sarcoma virus 17. It encodes a protein which is highly similar to the viral protein, and which interacts directly with specific target DNA sequences to regulate gene expression. This gene is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies. [provided by RefSeq, Jul 2008]

Jun: the protooncogene c-Jun is a component of the transcription factor AP-1, which binds and activates transcription at TRE/AP-1 elements. The Jun Kinases (JNKs) binds to the N-terminal region of c-Jun and phosphorylate it in response to extracellular signals including growth factors, cytokines and stress, regulating its transcriptional activity.
