Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables several functions, including DNA-binding transcription factor binding activity; E-box binding activity; and protein heterodimerization activity. Contributes to DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in gastrulation; positive regulation of neuron differentiation; and positive regulation of transcription by RNA polymerase II. Acts upstream of with a positive effect on transcription by RNA polymerase II. Acts upstream of or within several processes, including immune system development; lymphocyte differentiation; and regulation of gene expression. Located in cytosol and nucleus. Part of RNA polymerase II transcription regulator complex and nucleosome. Is expressed in several structures, including brain; branchial arch; genitourinary system; integument; and retina. Used to study acute lymphoblastic leukemia. Human ortholog(s) of this gene implicated in agammaglobulinemia 8A; agammaglobulinemia 8B; and colorectal cancer. Orthologous to human TCF3 (transcription factor 3).
