Extracellular matrix serine protease that plays a role in layering of neurons in the cerebral cortex and cerebellum. Regulates microtubule function in neurons and neuronal migration. Affects migration of sympathetic preganglionic neurons in the spinal cord, where it seems to act as a barrier to neuronal migration. Enzymatic activity is important for the modulation of cell adhesion. Binding to the extracellular domains of lipoprotein receptors VLDLR and LRP8/APOER2 induces tyrosine phosphorylation of DAB1 and modulation of TAU phosphorylation. Defects in RELN are the cause of lissencephaly type 2 (LIS2); also known as lissencephaly with cerebellar hypoplasia or Norman-Roberts syndrome. LIS2 is a classic type lissencephaly associated with abnormalities of the cerebellum, hippocampus and brainstem. Individuals with LIS2 are severely ataxic, mentally retarded and suffer from epilepsy. Belongs to the reelin family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
