Lmx1b Gene Summary [Mouse]
Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including memory; olfactory behavior; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including collagen fibril organization; nervous system development; and trabecular meshwork development. Located in nucleus. Is expressed in several structures, including central nervous system; embryo ectoderm; embryo mesenchyme; limb; and limb bud. Used to study Parkinson's disease and nail-patella syndrome. Human ortholog(s) of this gene implicated in nail-patella syndrome. Orthologous to human LMX1B (LIM homeobox transcription factor 1 beta). [provided by Alliance of Genome Resources, Apr 2025]

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 mouse Lmx1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
