UPAR_LY6_2 is a family of higher eukaryotic proteins expressed in neurons. It modulates nicotinic acetylcholine receptors by selectively increasing Ca2+-influx through this ion channel [1]. The family carries an LU protein domain - about 80 amino acids long characterised by a conserved pattern of 10 cysteine residues [2]. The family is a positive feedback regulator of Wnt/beta-catenin signalling, eg for patterning of the mesoderm and neuroectoderm in zebrafish gastrulation, where Lypd6 is GPI-anchored to the plasma-membrane and interacts with the Wnt receptor Frizzled8 and the co-receptor Lrp6 [3].
