Summary: Predicted to enable small GTPase binding activity. Involved in several processes, including axon development; cytoskeleton organization; and epithelial cell differentiation. Located in several cellular components, including microvillus; neuromuscular junction; and rhabdomere. Part of protein-containing complex. Is expressed in several structures, including adult head; embryonic salivary gland duct; embryonic ventral epidermis; embryonic/larval neuromuscular junction; and epithelium. Human ortholog(s) of this gene implicated in Wiskott-Aldrich syndrome; X-linked severe congenital neutropenia; and thrombocytopenia. Orthologous to several human genes including WAS (WASP actin nucleation promoting factor). [provided by Alliance of Genome Resources, Dec 2024]

along with controlling membrane binding, these autoregulatory interactions inhibit the ability of Nwk-SH3a to activate Wiskott-Aldrich syndrome protein (WASp)/actin related protein (Arp) 2/3-dependent actin filament ..we define structural rearrangements in Nwk that control F-BAR-membrane interactions as well as SH3 domain activities, and suggest that these two functions are tightly coordinated in vitro and in vivo.
