Hmgn3 - high mobility group nucleosomal binding domain 3

Enables chromatin binding activity. Acts upstream of or within positive regulation of DNA-binding transcription factor activity; positive regulation of transcription by RNA polymerase II; and regulation of insulin secretion involved in cellular response to glucose stimulus. Located in nucleus. Is expressed in several structures, including brain; epithelium; eye; genitourinary system; and limb. Orthologous to human HMGN3 (high mobility group nucleosomal binding domain 3). [provided by Alliance of Genome Resources, Apr 2022]
