Mouse LRRN1 Protein

Recombinant Mouse LRRN1 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ser26-Ala631. Lrrn1 is required for the formation of MHB--loss of function leads to a loss of the morphological constriction and loss of Fgf8. Cells overexpressing Lrrn1 violate the boundary and result in a loss of cell restriction between midbrain and hindbrain compartments. Lrrn1 also regulates the glycosyltransferase Lunatic Fringe, a modulator of Notch signalling, maintaining its expression in midbrain cells which is instrumental in MHB boundary formation.
