Summary
Predicted to enable DNA binding activity; IMP dehydrogenase activity; and identical protein binding activity. Involved in retina development in camera-type eye. Predicted to be located in nucleus. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in Leber congenital amaurosis 11; retinitis pigmentosa; and retinitis pigmentosa 10. Orthologous to human IMPDH1 (inosine monophosphate dehydrogenase 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
