Protein assembly at the post synaptic density (PSD) of neuronal synapses is mediated in part by protein interactions with PDZ (PSD-95/discs large/zona occludens-1) motifs. The Mammalian LIN-7 (MALS) proteins are a family of small synaptic proteins that are the mammalian homologs of LIN-7, a C. elegans protein essential for vulval development. MALS proteins are also known as Veli (Vertebrate Lin-7) proteins. MALS-3 mRNA is most abundant in kidney, followed by brain, liver, thymus and heart. MALS-3 is undetectable in spleen. In cultured cortical neurons, MALS proteins are clustered together with PSD-95 and NMDA-type glutamate receptors. MALS proteins are suggested to have roles in regulating the recruitment of neurotransmitter receptors to the PSD and in the assembly of proteins involved in synaptic vesicle exocytosis and synaptic junctions.
