Reelin's name comes from the abnormal reeling gait of reeler mice, [17] which were later found to have a deficiency of this brain protein and were homozygous for mutation of the RELN gene. The primary phenotype associated with loss of reelin function is a failure of neuronal positioning throughout the developing central nervous system (CNS).
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.
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 ...
It was found later that the mutation causing these disorders was located in the RELN gene which codes for reelin, a glycoprotein secreted by Cajal–Retzius cells in the developing brain. This protein seems to act as a stop signal for migrating neurons, controlling the positioning and orientation of neurons in their layers, according to the ...
Reference notes. A reference card or reference sheet (or quick reference card) or crib sheet is a concise bundling of condensed notes about a specific topic, such as mathematical formulas [1] to calculate area/volume, or common syntactic rules and idioms of a particular computer platform, application program, or formal language.
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]
Regelation is the phenomenon of ice melting under pressure and refreezing when the pressure is reduced. This can be demonstrated by looping a fine wire around a block of ice, with a heavy weight attached to it. The pressure exerted on the ice slowly melts it locally, permitting the wire to pass through the entire block.
Summer Insolation drive temperature responses that have an effect on the rate of melting and mass balance of the ice sheet. [16] For example, the dependence of ice volume on summer insolation can be represented with () = (), where I is ice volume, () is the rate of change of ice volume per unit of time, T is the response time of the ice sheet ...
