Summary: Enables actin filament binding activity and protein-macromolecule adaptor activity. Involved in formin-nucleated actin cable assembly. Located in actin cortical patch and actin filament bundle. Used to study Huntington's disease. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 76; congenital diaphragmatic hernia; and nicotine dependence. Orthologous to human LCP1 (lymphocyte cytosolic protein 1); PLS1 (plastin 1); and PLS3 (plastin 3). [provided by Alliance of Genome Resources, Nov 2024]

NP_010414.3

Fimbrin, actin-bundling protein; cooperates with Scp1p in organization and maintenance of the actin cytoskeleton; phosphorylated by Cdc28p/Clb2p in metaphase on T103, to regulate conformation, and modulate actin filament binding affinity and actin cable dynamics; relocalizes from the plasma membrane to the cytoplasm upon DNA replication stress; human homologs PLS3 and LCP1 implicated in spinocerebellar ataxia type 2 (SCA2) can each complement yeast null mutant
