Function |
Regulator of cell surface receptor signal transduction. Acts as a regulator of membrane proteinases such as ADAM10 and MMP14/MT1-MMP. Activates ADAM10-dependent cleavage activity of amyloid precursor protein (APP). Activates MMP14/MT1-MMP-dependent cleavage activity (By similarity). Plays a central role in retinal vascularization by regulating norrin (NDP) signal transduction. Acts in concert with norrin (NDP) to promote FZD4 multimerization and subsequent activation of FZD4, leading to promote accumulation of beta-catenin (CTNNB1) and stimulate LEF/TCF-mediated transcriptional programs. Suprisingly, it only activate the norrin (NDP)-dependent activation of FZD4, while it does not activate the Wnt-dependent activation of FZD4, suggesting the existence of a Wnt-independent signaling that also promote accumulation the beta- catenin (CTNNB1). {ECO:0000250, ECO:0000269|PubMed:19837033}.

Tissue Specificity |
Expressed in the neonatal retinal vasculature but not other retinal tissues. Also detected in the neonatal meningeal vasculature and in nonvascular cell types, such as the smooth muscle cells in the neonatal intestine. {ECO:0000269|PubMed:19837033}.
