Id1 - inhibitor of DNA binding 1, HLH protein

Enables protein self-association and transcription regulator inhibitor activity. Involved in negative regulation of cold-induced thermogenesis; negative regulation of transcription, DNA-templated; and positive regulation of gene expression. Acts upstream of or within several processes, including endothelial cell morphogenesis; lung development; and negative regulation of macromolecule metabolic process. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Orthologous to human ID1 (inhibitor of DNA binding 1, HLH protein). [provided by Alliance of Genome Resources, Apr 2022]
