Predicted to enable actin filament binding activity. Predicted to be involved in several processes, including actin filament organization; inner ear receptor cell stereocilium organization; and intestinal D-glucose absorption. Predicted to act upstream of or within terminal web assembly. Predicted to be located in brush border; stereocilium; and terminal web. Predicted to be active in actin filament; actin filament bundle; and cytoplasm. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 76. Orthologous to human PLS1 (plastin 1). [provided by Alliance of Genome Resources, Apr 2022]
