JAG1, expressed on a neighboring cell, binds NOTCH2 and activates intracellular NOTCH2 signaling (Shimizu et al. 1999, Shimizu et al. 2000). In contrast to NOTCH1, where fringe-mediated modification reduces the affinity of JAG1 for NOTCH1, it seems that fringe-mediated modification of NOTCH2 extracellular domain enhances activation of NOTCH2 signaling by JAG1 (Hicks et al. 2000).

JAG1-NOTCH2 signaling axis is affected in Alagille syndrome (AGS), a dominant congenital disorder characterized by hepatic bile duct abnormalities, as well as craniofacial, heart and kidney defects (Alagille et al. 1975, Habib et al. 1987). AGS is predominantly caused by mutations in JAG1 (Oda et al. 1997, Li et al. 1997) and less frequently by mutations in NOTCH2 (McDaniell et al. 2006).

JAG1 and NOTCH2 are expressed in kidney glomeruli and JAG1-NOTCH2 signaling plays an important role in kidney development, as shown in mice mutant for JAG1 or NOTCH2 or both (McCright et al. 2001, McCright et al. 2002).

NOTCHNLs, highly similar human-specific proteins encoded by Hominidae-specific NOTCH2NLA, NOTCH2NLB, and NOTCH2NLC genes that originate from the partial duplication of the NOTCH2 gene, stimulate NOTCH signaling (Fiddes et al. 2018, Suzuki et al. 2018) both in the presence and absence of the in trans DLL1, DLL4, and JAG2 ligands (Fiddes et al. 2018). JAG1 ligand was not directly studied in this context, but the regulation is inferred from the positive regulation of JAG2-stimulated NOTCH signaling. As a recombinant NOTCH2NLB was used in functional studies, NOTCH2NLB is annotated as a set member, while NOTCH2NLA and NOTCH2NLC are annotated as set candidates in this reaction showing the binding of JAG1 to NOTCH2. Although NOTCH1, NOTCH2, and NOTCH3 reporters were used to measure NOTCHNL-mediated activation of NOTCH signaling, the activity of NOTCH2NLs is only shown in the context of NOTCH2 signaling for several reasons. NOTCH2NLs are co-expressed with NOTCH2 due to promoter region of NOTCH2 being part of the duplicated segment (Fiddes et al. 2018, Suzuki et al. 2018), they likely act in cis, and are they are most similar in sequence to NOTCH2.
