    Summary
    Enables identical protein binding activity. Involved in regulation of fat cell differentiation. Acts upstream of or within negative regulation of Notch signaling pathway. Predicted to be located in membrane. Predicted to be integral component of membrane. Is expressed in several structures, including articular cartilage; foregut; limb mesenchyme; long bone; and nasal cavity respiratory epithelium. Orthologous to human DLK2 (delta like non-canonical Notch ligand 2). [provided by Alliance of Genome Resources, Apr 2022]

    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.
