Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; bHLH transcription factor binding activity; and protein homodimerization activity. Involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; negative regulation of DNA-binding transcription factor activity; and trophoblast giant cell differentiation. Located in nucleolus and nucleoplasm. Is expressed in several structures, including alimentary system; early conceptus; heart and pericardium; nervous system; and urinary system. Orthologous to human HAND1 (heart and neural crest derivatives expressed 1). PHENOTYPE: Homozygotes for targeted null mutations die at embryonic day 8.5-9.5 with yolk sac abnormalities associated with a deficiency of extraembryonic mesoderm and defective trophoblast differentiation. Tetraploid chimeric rescue slightly extends development. [provided by MGI curators] |
