It regulates microtubule function in neurons and neuronal migration. It binds to the extracellular domains of lipoprotein receptors VLDLR and LRP8/APOER2 which induces tyrosine phosphorylation of DAB1 and modulation of TAU phosphorylation. Reelin consists of a signal sequence, an F-spondin-like region and nine sequentially concatenated repeat units. Each complete reelin repeat contains a central epidermal growth factor (EGF) module flanked by two subrepeats of 150-190 amino acids (subrepeats A and B) [1-3]. This entry represents subrepeat B (also referred to R3B) which adopts a beta jelly-roll fold similar to bacterial xylanase. They contain the signature Asp-box motif [1-3].
