Summary: Predicted to enable transcription corepressor activity. Involved in BMP signaling pathway. Acts upstream of or within several processes, including mitotic intra-S DNA damage checkpoint signaling; regulation of Notch signaling pathway; and regulation of cell proliferation involved in compound eye morphogenesis. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; eye; immature eye; mesoderm; and neural crest. Orthologous to human ID2 (inhibitor of DNA binding 2). [provided by Alliance of Genome Resources, Dec 2024]

Mosaic analyses reveal that Id2a function in facilitating both cell cycle progression and neuronal differentiation in the retina is non-cell-autonomous, suggesting that Id2a functions upstream of the extrinsic pathways that regulate retinogenesis.

id2 is expressed in the tegmentum; midbrain-hindbrain boundary; cerebellum; rhombomeres 2,3,4,6; notochord; and corpuscles of Stannius, and is repressed in mind bomb mutants, suggesting a role of Notch upstream of Id2.

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.
