Involved in controlling patterning and neuronal circuit formation at the laminar, cellular, subcellular and synaptic levels. Promotes neurite outgrowth of both axons and dendrites. Interacts with LRRC4. The laminin N-terminal domain mediates 1:1 binding to NGL ligand with sub-micromolar affinity. Three NGL-binding loops mediate discrimination for LRRC4C/NGL1 among other NGLs by binding specifically to its LRR repeats. This specificity drives the sorting of a mixed population of molecules into discrete cell surface subdomains. N-glycosylated. The disease is caused by variants affecting the gene represented in this entry. Extended N-terminus.
