ARF3 Protein, Human (His)

ARF3 protein, a GTP-binding allosteric activator of cholera toxin, plays a role in protein trafficking and vesicle dynamics in the Golgi apparatus. Beyond toxin activation, ARF3 interacts with PRKCABP, participating in diverse cellular processes. It also associates with PI4KB and NCS1/FREQ at the Golgi complex, emphasizing its role in crucial molecular interactions for cellular functions. ARF3 Protein, Human (His) is the recombinant human-derived ARF3 protein, expressed by E. coli , with N-His labeled tag. The total length of ARF3 Protein, Human (His) is 181 a.a., with molecular weight of ~23 kDa.

ARF3, a GTP-binding protein, acts as an allosteric activator of the catalytic subunit of cholera toxin, an ADP-ribosyltransferase. Beyond its role in toxin activation, ARF3 is implicated in protein trafficking, exerting potential influence on vesicle budding and uncoating within the Golgi apparatus. This multifaceted protein interacts with PRKCABP, highlighting its involvement in various cellular processes. Additionally, ARF3 associates with PI4KB and NCS1/FREQ at the Golgi complex, further emphasizing its participation in molecular interactions crucial for cellular functions.
