Background Information

What is the molecular weight of JUN?

The molecular weight of JUN is approximately 39 kDa.

What is the cellular localization of JUN?

JUN expression can be located in the nucleus. However, ubiquitinated JUN colocalizes with lysosomal proteins (PMID: 15469925).

 What is the function of JUN?

JUN is a basic leucine zipper (bZIP) transcription factor that recognizes and binds to a consensus heptamer motif of 5’-TGA[CG]TCA-3’ in the enhancer region of target genes. JUN acts as either a homo- or heterodimer and binds to the DNA to regulate transcriptional activity, specifically promoting the activity of NR5A1 when phosphorylated by HIPK3, leading to increased steroidogenic gene expression upon the stimulation of the cAMP signaling pathway (PMID: 9732876).

 What post-translational modifications is JUN subjected to?

JUN is acetylated at Lys-271 by EP300 (PMID: 11689449). JUN is phosphorylated by PLK3 following exposure to hypoxia or UV irradiation, which leads to increased DNA-binding activity (PMID: 27281822), and also by PAK2 at numerous threonine residues to promote cell proliferation and transformation (PMID: 21177766). JUN is also phosphorylated by DYRK2 at Ser-243, which primes it for subsequent further phosphorylation by GSK3B and reduces its ability to bind DNA (PMID: 22307329).

 What is the role of JUN in disease?

Activation of JUN is linked with proliferation and angiogenesis in invasive breast cancers (PMID: 16733206).
