Gene Information
Gene Symbol
AP-1, AP1, c-Jun
Entrez Gene ID
Gene Name
Jun proto-oncogene
Chromosomal Location
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)
