Developmental stage

Expressed in fetal and postnatal brain and liver. Expression in postnatal human brain is high in the cerebellum.

Domain

The basic C-terminal region is essential for secretion.

Function

Extracellular matrix serine protease secreted by pioneer neurons that plays a role in layering of neurons in the cerebral cortex and cerebellum by coordinating cell positioning during neurodevelopment. Regulates microtubule function in neurons and neuronal migration. Binding to the extracellular domains of lipoprotein receptors VLDLR and LRP8/APOER2 induces tyrosine phosphorylation of DAB1 and modulation of TAU phosphorylation. 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.

Involvement in disease

Lissencephaly 2

LIS2

A classic type lissencephaly associated with ataxia, intellectual disability, seizures and abnormalities of the cerebellum, hippocampus and brainstem.

None

The disease is caused by variants affecting the gene represented in this entry.

Epilepsy, familial temporal lobe, 7

ETL7

A focal form of epilepsy characterized by recurrent seizures that arise from foci within the temporal lobe. Seizures are usually accompanied by sensory symptoms, most often auditory in nature.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

N-glycosylated and to a lesser extent also O-glycosylated.

Sequence similarities

Belongs to the reelin family.

Tissue specificity

Abundantly produced during brain ontogenesis by the Cajal-Retzius cells and other pioneer neurons located in the telencephalic marginal zone and by granule cells of the external granular layer of the cerebellum. In adult brain, preferentially expressed in GABAergic interneurons of prefrontal cortices, temporal cortex, hippocampus and glutamatergic granule cells of cerebellum. Expression is reduced to about 50% in patients with schizophrenia. Also expressed in fetal and adult liver.
