Function:
Domain:The Delta-Serrate-Lag2 (DSL) domain is required for binding to the Notch receptor.,Function:Plays a role in the Notch signaling pathway. Activates Notch-1 and Notch-4.,PTM:Ubiquitinated by MIB (MIB1 or MIB2), leading to its endocytosis and subsequent degradation.,similarity:Contains 1 DSL domain.,similarity:Contains 8 EGF-like domains.,subunit:Binds to Notch-1 and Notch-4.,tissue specificity:Expressed in vascular endothelium.,
