JUN(Jun proto-oncogene, AP-1 transcription factor subunit) 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. JUN is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies.基因ID为:3725;蛋白质ID:P05427
