Tcf3 Gene Summary [Rat]

Enables PDZ domain binding activity and bHLH transcription factor binding activity. Contributes to E-box binding activity. Involved in positive regulation of DNA-templated transcription and positive regulation of gene expression. Part of transcription regulator complex. Human ortholog(s) of this gene implicated in agammaglobulinemia 8A; agammaglobulinemia 8B; and colorectal cancer. Orthologous to human TCF3 (transcription factor 3).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Tcf3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
