Reelin, encoded by the RELN gene, [5] is a large secreted extracellular matrix glycoprotein that helps regulate processes of neuronal migration and positioning in the developing brain by controlling cell–cell interactions. Besides this important role in early development, reelin continues to work in the adult brain. [6]
The Disabled-1 (Dab1) gene encodes a key regulator of Reelin signaling. Reelin is a large glycoprotein secreted by neurons of the developing brain, particularly Cajal-Retzius cells. DAB1 functions downstream of Reln in a signaling pathway that controls cell positioning in the developing brain and during adult neurogenesis.
In genetics, rs7341475 is a single nucleotide polymorphism (SNP) in the RELN gene that codes the reelin protein. The gene RELN is mapped to human chromosome 7 (7q22.1). The SNP rs7341475 is located in the fourth intron of RELN. The gene RELN has many more SNPs among its 65 exons and 64 introns, — even in intron 4 there are tens of SNPs. [1]
ApoE competes with reelin in binding to ApoER2 resulting in weakened reelin signaling. Reduced reelin signaling leads to impaired plasticity in neurons and increases in the phosphorylation of tau protein, which is a microtubule stabilizing protein that is abundant in the Central Nervous System (CNS), producing neurofibrillary tangles which are ...
The product of the reeler gene in mouse is reelin, a large extracellular protein secreted by pioneer neurons that coordinates cell positioning during neurodevelopment. [1] F-spondin and mindin are a family of matrix-attached adhesion molecules that share structural similarities and overlapping domains of expression. Both F-spondin and mindin ...
There are also a number of genetic causes of lissencephaly, including mutation of the reelin gene (on chromosome 7), [7] as well as other genes on the X chromosome and on chromosome 17. Genetic counseling is usually offered if there is a risk of lissencephaly, coupled with genetic testing.
Rosacea. What it looks like: Rosacea causes redness and thick skin on the face, usually clustered in the center.Easy flushing, a stinging sensation, and small, pus-filled pimples are other common ...
The reelin pathway, representing VLDLR’s role in the process. In addition to its role throughout the body, VLDLR has a unique role in the brain. It is a key component of the reelin pathway, which functions on one hand side in neuronal migration during the development of the brain, on the other hand in the retention of new memory traces in the ...
