{{Short description|Mammalian protein found in Homo sapiens}} {{Infobox_gene}} '''Actin-related protein 3''' is a protein that in humans is encoded by the ''ACTR3'' gene.<ref name="pmid9230079">{{cite journal | vauthors = Welch MD, DePace AH, Verma S, Iwamatsu A, Mitchison TJ | title = The human Arp2/3 complex is composed of evolutionarily conserved subunits and is localized to cellular regions of dynamic actin filament assembly | journal = The Journal of Cell Biology | volume = 138 | issue = 2 | pages = 375–84 | date = Jul 1997 | pmid = 9230079 | pmc = 2138188 | doi = 10.1083/jcb.138.2.375 }}</ref>

== Function ==

The specific function of this gene has not yet been determined; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion.<ref name="entrez">{{cite web | title = Entrez Gene: ACTR3 ARP3 actin-related protein 3 homolog (yeast)| url = https://www.ncbi.nlm.nih.gov/gene?Db=gene&Cmd=ShowDetailView&TermToSearch=10096| access-date = }}</ref>

== Interactions ==

ACTR3 has been shown to interact with Cortactin.<ref name=pmid11018051>{{cite journal | vauthors = Weed SA, Karginov AV, Schafer DA, Weaver AM, Kinley AW, Cooper JA, Parsons JT | title = Cortactin localization to sites of actin assembly in lamellipodia requires interactions with F-actin and the Arp2/3 complex | journal = The Journal of Cell Biology | volume = 151 | issue = 1 | pages = 29–40 | date = Oct 2000 | pmid = 11018051 | pmc = 2189811 | doi = 10.1083/jcb.151.1.29 }}</ref><ref name=pmid12176742>{{cite journal | vauthors = Di Ciano C, Nie Z, Szászi K, Lewis A, Uruno T, Zhan X, Rotstein OD, Mak A, Kapus A | title = Osmotic stress-induced remodeling of the cortical cytoskeleton | journal = American Journal of Physiology.
