ATF2


Also found in: Acronyms.

ATF2

A gene on chromosome 2q32 that encodes a transcription factor of the leucine zipper family of DNA binding proteins, which binds to the cAMP-responsive element (CRE) and stimulates CRE-dependent transcription.

This work also reveals that the ratio of ATF2 to MITF in the nucleus of melanoma cells can predict survival in melanoma patients - relatively high amounts of ATF2 and correspondingly low MITF levels were associated with a poor prognosis.
disrupted the ATF2 gene in the melanocytes of mice harboring mutations often seen in human melanoma.
They showed that diatrizoate, iodixanol, and iothalamate, but interestingly not iohexol, induced the expression of ATF-2 (activating transcription factor-2) mRNA and phosphorylation of ATF2 in HEK293T cells in a time-dependent manner.
Once activated, the p38 MAPK pathway initiates the production of transcription factors including PAX6, p53, ATF1, ATF2, and CREB and regulates the production of proinflammatory or apoptosis-associated genes [26, 27].

Activating transcription factor 2 (ATF2) is a transcription factor of the leucine zipper family of DNA-binding proteins, discovered in 1991 by Ozawa et al.
Principally, ERK is responsible for cell survival, because it can regulate c-Myc, activator protein 1 (AP-1), and B cell lymphoma-2 (Bcl-2) [59], while p53, nuclear factor-[kappa]B (NF-[kappa]B), and activating transcription factor 2 (ATF2) are the targets for p38.
In HUVEC, an increased nuclear translocation of some components of these transcription factors was observed (p65 and p50 for NF[kappa]B and c-jun, cfos, and ATF2 for AP1) [100].
