ARF-like small GTPases; ARF, ADP-ribosylation factor
SMART accession number:SM00177
Description: Ras homologues involved in vesicular transport. Activator of phospholipase D isoforms. Unlike Ras proteins they lack cysteine residues at their C-termini and therefore are unlikely to be prenylated. ARFs are N-terminally myristoylated. Contains ATP/GTP-binding motif (P-loop).
