CHAC1 Protein, Human (StrepⅡ)

The CHAC1 protein cleaves glutathione, inducing apoptosis via the ATF4-ATF3-DDIT3/CHOP cascade. It acts as a negative regulator of the Notch signaling pathway, promoting neurogenesis by inhibiting Notch cleavage. CHAC1 Protein, Human is the recombinant human-derived CHAC1 protein, expressed by E. coli , with C-Strep. The total length of CHAC1 Protein, Human is 221 a.a., .

CHAC1, a key player in cellular processes, catalyzes the cleavage of glutathione into 5-oxo-L-proline and a Cys-Gly dipeptide, exhibiting specificity for glutathione over other gamma-glutamyl peptides. Its enzymatic action on glutathione is crucial as glutathione depletion is a significant factor in apoptosis initiation and execution. CHAC1 further serves as a pro-apoptotic component within the unfolded protein response pathway, mediating the effects of the ATF4-ATF3-DDIT3/CHOP cascade. Additionally, CHAC1 functions as a negative regulator of the Notch signaling pathway, impacting embryonic neurogenesis by inhibiting Notch cleavage through furin. This inhibition maintains Notch in an immature, inactive form, thereby promoting neurogenesis in embryos.
