Summary: Predicted to enable ATPase binding activity; actin filament binding activity; and glutamate receptor binding activity. Predicted to be a structural constituent of cytoskeleton. Acts upstream of or within positive regulation of actin filament polymerization and positive regulation of substrate adhesion-dependent cell spreading. Located in several cellular components, including endosome; focal adhesion; and muscle cell projection membrane. Is active in glutamatergic synapse; postsynapse; and synaptic vesicle membrane. Is expressed in lens and lens pit. Orthologous to human ARPC2 (actin related protein 2/3 complex subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Study shows that the T-cell-specific deletion of Arpc2 results in compromised peripheral T-cell homeostasis suggesting that ARPC2 is essential for T-cell homeostasis probably by maintaining surface TCR levels via regulating TCR(+) endosome trafficking.
Title: Arp2/3 complex controls T cell homeostasis by maintaining surface TCR levels via regulating TCR(+) endosome trafficking.
WASH is a bimodular protein and a component of the BLOC-1 complex in which the C terminus is involved in Arp2/3-mediated actin nucleation, whereas the N-terminal portion is required for its regulation and localization in the cells
Title: Functional characterization of Wiskott-Aldrich syndrome protein and scar homolog (WASH), a bi-modular nucleation-promoting factor able to interact with biogenesis of lysosome-related organelle subunit 2 (BLOS2) and gamma-tubulin.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
