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 ...

Thomae's function: is a function that is continuous at all irrational numbers and discontinuous at all rational numbers. It is also a modification of Dirichlet function and sometimes called Riemann function. Kronecker delta function: is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise.
For example, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation. [ 2 ] [ 3 ] Thus, in the expression 1 + 2 × 3 , the multiplication is performed before addition, and the expression has the value 1 + (2 × 3) = 7 , and not (1 + 2) × 3 = 9 .
In spreadsheet programs like the open source LibreOffice Calc or Microsoft's Excel, a single document is known as a 'workbook' and may have by default three arrays or 'worksheets'. One advantage of such programs is that they can contain formulae so that if one cell value is changed, the entire document is automatically updated, based on those ...
