Function
Activating transcription factor 4 (tax-responsive enhancer element B67), also known as ATF4, is a protein that in humans is encoded by the ATF4 gene. ATF4 transcription factor is also known to play role in osteoblast differentiation along with RUNX2 and osterix. Terminal osteoblast differentiation, represented by matrix mineralization, is significantly inhibited by the inactivation of JNK. JNK inactivation downregulates expression of ATF-4 and, subsequently, matrix mineralization. IMPACT protein regulates ATF4 in C. elegans to promote lifespan. ATF4 is also involved in the cannabinoid Δ9-tetrahydrocannabinol–induced apoptosis in cancer cells, by the proapoptotic role of the stress protein p8 via its upregulation of the endoplasmic reticulum stress-related genes ATF4, CHOP, and TRB3.

Predicted band size: 39 kDa
Observed band size: 50 kDa
Exposure time: 2 minutes; ECL: K1801;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA751130) at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. -

☑ Cell treatment (CT)
ATF4 was immunoprecipitated from 0.2 mg HeLa treated with 2μg/mL Tunicamycin for 8 hours cell lysate with HA751130 at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using HA751130 at 1/1,000 dilution. Anti-Rabbit IgG for IP Nano-secondary antibody (NBI01H) at 1/5,000 dilution was used for 1 hour at room temperature.
