Gene Information

General description

Neurabin II belongs to a family of F-actin-binding proteins, highly enriched in dendritic spines and involved in neurite formation. It consists of an F-actin binding domain at the N-terminus, a single PDZ-interacting-domain and a C-terminal coiled-coil domain.

Immunogen

synthetic peptide corresponding to amino acids 800-817 located at the C-terminal region of rat neurabin II. The sequence is identical in human and mouse neurabin II and not found in neurabin I.

Application

Anti-Neurabin II (C-terminal) antibody has been used in
  • immunoblotting
  • immunoprecipitation
  • immunocytochemistry

Biochem/physiol Actions

Neurabins appear to function as bridging proteins by targeting other proteins to the synapse or by linking plasma membrane proteins to the actin cytoskeleton. Neurabin II binds to several proteins including F-actin, protein phosphatase 1 (PP1), at least two subfamilies of G-protein coupled receptors (GPCRs), the α2 adrenergic receptor (α2AR) subtypes and the D2 dopamine receptor. Neurabin II blocks arrestin function in vitro and in vivo at GPCRs and has been also shown to modulate, in vitro and in vivo, both glutaminergic synaptic transmission and the formation and function of dendritic spines. Neurabin II and neurabin I target PP1 subunits that are highly concentrated in dendritic spines and post-synaptic densities. Phosphorylation of neurabin II modulates its interaction with actin filaments, via the anchoring of the neurabin II-PP1 complex within dendritic spines, thereby contributing to the efficacy and plasticity of synaptic transmission.
