Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables several functions, including bHLH transcription factor binding activity; leptomycin B binding activity; and transcription regulator inhibitor activity. Involved in several processes, including negative regulation of myoblast differentiation; notochord development; and regulation of gene expression. Acts upstream of or within several processes, including cellular response to leptomycin B; negative regulation of macromolecule biosynthetic process; and negative regulation of osteoblast differentiation. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; limb; metanephros; and sensory organ. Used to study Sjogren's syndrome. Orthologous to human ID3 (inhibitor of DNA binding 3).
