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 NGL1. Highly expressed in the thalamus, with very low expression, if any, in other tissues. 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. Mostly expressed in adult brain. Hi expression in Expressed in brain and. Mostly expressed in kidney, also expressed in adult and fetal brain. Some expression in fetal brain. Extended N-terminus.
