Summary: Contributes to actin filament binding activity. Acts upstream of or within barbed-end actin filament capping. Located in several cellular components, including brush border; cell-cell junction; and cortical cytoskeleton. Part of F-actin capping protein complex. Is expressed in early conceptus; head mesenchyme; and lung. Orthologous to human CAPZA1 (capping actin protein of muscle Z-line subunit alpha 1). [provided by Alliance of Genome Resources, Dec 2024]

Here, the authors discover that the C-terminal tail of Twinfilin harbors a capping protein-interacting (CPI) motif, identifying it as a novel CPI-motif protein. Twinfilin binds competitively with CARMIL to capping protein, protecting capping protein from barbed-end displacement by CARMIL.

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.
