Enables protein homodimerization activity. Involved in axon target recognition; regulation of synapse assembly; and synaptic assembly at neuromuscular junction. Part of protein-containing complex. Is active in neuromuscular junction. Is expressed in eye disc; eye disc morphogenetic furrow; and organism. Orthologous to several human genes including PPFIBP2 (PPFIA binding protein 2).
FB Description
Liprin-beta (Liprin-beta) encodes an adaptor protein that can interact with the product of Liprin-alpha. It is required for normal photoreceptor axon targeting and neuromuscular junction development.
