Reelin (RL) ELISA Kit for Mouse

This gene encodes a large secreted extracellular matrix protein thought to control cell-cell interactions critical for cell positioning and neuronal migration during brain development. This protein may be involved in schizophrenia, autism, bipolar disorder, major depression and in migration defects associated with temporal lobe epilepsy. Mutations of this gene are associated with autosomal recessive lissencephaly with cerebellar hypoplasia. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]

reelin: 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.
