Is predicted to encode a protein with the following domains: Neurabin-1/2, PDZ domain; SAM domain (Sterile alpha motif); PDZ domain; PDZ superfamily; Sterile alpha motif/pointed domain superfamily; and Sterile alpha motif domain. Is an ortholog of C. elegans
nab-1. In C. elegans,
nab-1 is involved in synapse assembly.
