ARF1, Recombinant, Human (ADP-ribosylation Factor 1)

ARF1, also known as ADP-ribosylation factor 1, is a small guanine nucleotide-binding protein that enhances the enzymatic activities of cholera toxin. It is essential and ubiquitous in eukaryotes, as this protein is involved in vesicular transport and functioning via phospholipase D activation. ARF1 plays a role in membrane traffic and organelle integrity and are intimately tied to their reversible association with membranes and distinct interactions with membrane phospholipids.\n\nSource:\nRecombinant corresponding to aa1-181 of human ARF1 protein, fused to His-tag at N-terminus, expressed in E.coli.\n\nAA Sequence:\nMGSSHHHHHH SSGLVPRGSH MGNIFANLFK GLFGKKEMRI LMVGLDAAGK TTILYKLKLG EIVTTIPTIG FNVETVEYKN ISFTVWDVGG QDKIRPLWRH YFQNTQGLIF VVDSNDRERV NEAREELMRM LAEDELRDAV LLVFANKQDL PNAMNAAEIT DKLGLHSLRH RNWYIQATCA TSGDGLYEGL DWLSNQLRNQ K\n\nMolecular Weight: 22.8kD (201aa) confirmed by MALDI-TOF\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
