Arf1 - ADP-ribosylation factor 1

Enables guanyl ribonucleotide binding activity; magnesium ion binding activity; and phospholipase D activator activity. Involved in several processes, including Golgi to transport vesicle transport; positive regulation of transport; and postsynapse organization. Located in cytosol and late endosome. Is active in glutamatergic synapse and postsynaptic density. Colocalizes with COPI-coated vesicle; Golgi apparatus; and peroxisomal membrane. Human ortholog(s) of this gene implicated in periventricular nodular heterotopia. Orthologous to human ARF1 (ADP ribosylation factor 1). [provided by Alliance of Genome Resources, Apr 2022]
