Gene Summary

Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks (By similarity). Seems to contact the pointed end of the daughter actin filament (By similarity). Required during embryogenesis for the developmental migration of tail hemocytes anteriorly, along the ventral midline (PubMed:25739458). (UniProt, P32392)

ACTIN-RELATED PROTEINS

Protein Family (UniProt)

Belongs to the actin family. ARP3 subfamily. (P32392)

Protein Signatures (InterPro)

Summaries

Gene Group (FlyBase)

ACTIN-RELATED PROTEIN 2/3 COMPLEX -: The Actin-related protein 2/3 complex is involved in the organization of the actin cytoskeleton, in particular, the nucleation of branched actin filaments. (Adapted from FBrf0144947).
ACTIN-RELATED PROTEINS -: Actin-related proteins (Arp) share significant sequence identity with actins. Arps broadly fall into two groups: nuclear Arps, involved in chromatin remodeling; and cytoplasmic Arps, associated with actin. (Adapted from PMID:21859859).

Protein Function (UniProtKB)

Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks (By similarity). Seems to contact the pointed end of the daughter actin filament (By similarity). Required during embryogenesis for the developmental migration of tail hemocytes anteriorly, along the ventral midline (PubMed:25739458).

Model Confidence:

Very high (pLDDT > 90)
Confident (90 > pLDDT > 70)
Low (70 > pLDDT > 50)
Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Additional comments

FlyBase Curator comment: 'Arp66B' renamed to 'Arp3' to rationalize the nomenclature of Actin-related protein (Arp) genes (by orthology with the mammalian and yeast genes) and better reflect community usage.
