Summary: Enables actin monomer binding activity; phosphatidylinositol-4,5-bisphosphate binding activity; and protein tyrosine kinase activity. Involved in barbed-end actin filament capping; positive regulation of cardiac muscle hypertrophy; and sequestering of actin monomers. Located in several cellular components, including filopodium; myofibril; and perinuclear region of cytoplasm. Colocalizes with ruffle membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human TWF1 (twinfilin actin binding protein 1). [provided by Alliance of Genome Resources, Dec 2024]

The results demonstrate that the conserved C-terminal tail of twinfilin is a multifunctional binding motif, which is crucial for interaction with the heterodimeric capping protein and for tethering twinfilin to phosphoinositide-rich membranes.

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.
