Summary: The Notch signaling pathway is an intercellular signaling mechanism that is essential for proper embryonic development. Members of the Notch gene family encode transmembrane receptors that are critical for various cell fate decisions. The protein encoded by this gene is one of several ligands that activate Notch and related receptors. Two transcript variants encoding different isoforms have been found for this gene.

Results showed that Jagged2 was highly expressed in paclitaxel-resistant triple negative breast cancer (TNBC) tissues and cells. Jagged2 expression was found to be associated with cancer stem cell (CSC) properties of TNBC cells. Jagged2 maintains CSC properties of TNBC cells and paclitaxel resistance via regulating microRNA-200.

Long noncoding RNA (lncRNA) ENST00000455974 was significantly associated with TNM stage and distant metastasis in patients with DNA mismatch repair-proficient colon cancer. ENST00000455974 was gradually increased across the colonic normal-adenoma-carcinoma-metastasis sequence. ENST00000455974 was mainly located in the nucleus of colon cancer cells and it promoted growth and metastasis through up-regulating JAG2.

In CL+/-P Malay patients, the prevalence of mutations in the Jagged2 gene was 12.5%. Three variants (g.19779C>T, g.19547G>A, and g.19712C>T) were identified in the Jagged2 gene among nonsyndromic CL+/-P and noncleft patients. Only g.19712C>T showed a significant association with nonsyndromic CL+/-P patients (P = .039).

The authors present novel structures of human ligands Jagged2 and Delta-like4 and human Notch2, together with functional assays, which suggest that ligand-mediated coupling of membrane recognition and Notch binding is likely to be critical in establishing the optimal context for Notch signalling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
