Ldb1 - LIM domain binding 1

Enables several functions, including LIM domain binding activity; protein homodimerization activity; and protein self-association. Contributes to DNA binding activity. Involved in several processes, including histone H3-K4 acetylation; negative regulation of erythrocyte differentiation; and regulation of cellular macromolecule biosynthetic process. Acts upstream of or within several processes, including cerebellar Purkinje cell differentiation; epithelial structure maintenance; and hair follicle development. Located in cell leading edge and nucleus. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including branchial arch; central nervous system; embryo mesenchyme; eye; and genitourinary system. Used to study nail-patella syndrome. Orthologous to human LDB1 (LIM domain binding 1). [provided by Alliance of Genome Resources, Apr 2022]
