pfam16975: UPAR_LY6_2 (This model is not part of the current CDD release)
Ly6/PLAUR domain-containing protein 6, Lypd6
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. The family carries an LU protein domain - about 80 amino acids long characterised by a conserved pattern of 10 cysteine residues. 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.
