General annotation (Comments)

Function	Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. May be a signaling molecule important in CNS development. Is likely to signal over only few cell diameters. Proeminent role in the induction of the mesencephalon and cerebellum. May play a crucial role in the morphogenesis of the neural tube and/or the early stages of CNS development. Ref.5
Subunit structure	Interacts with PORCN. Interacts with RSPO1, RSPO2 and RSPO3. Ref.8 Ref.9
Subcellular location	Secreted › extracellular space › extracellular matrix.
Tissue specificity	Testis and mid-gestational embryos. In the testis, detected only in postmeiotic germ cells undergoing differentiation from round spermatids into mature spermatozoa. In the embryos, expression is restricted to the developing CNS in regions of the neural tube other than the telencephalon. Ref.7
Developmental stage	Accumulates throughout the neural plate at the anterior head folds of the 9 day embryo but only at its lateral tips in more posterior regions. Following neural tube closure, expression is restricted to specific regions of the dorsal wall of the brain ventricles and spinal cord, the ventral wall of the midbrain and the diencephalon, and the lateral walls of the neuroepithelium at the midbrain-hindbrain junction. Ref.6
Involvement in disease	Many mouse mammary tumors induced by mouse mammary tumor virus (MMTV) contain a provirus integrated into a host cell region which has been named INT-1 (now Wnt1).
Sequence similarities	Belongs to the Wnt family.
