Is predicted to encode a protein with the following domains: Liprin-beta; Sterile alpha motif domain; Sterile alpha motif/pointed domain superfamily; LAR-interacting protein, Liprin; and SAM domain (Sterile alpha motif). Is an ortholog of C. elegans hlb-1. In C. elegans, hlb-1 is involved in neuromuscular junction development; positive regulation of locomotion; and regulation of nematode pharyngeal pumping.
