Gene: Hmg20a (high mobility group 20A) Mus musculus
Symbol: Hmg20a
Name: high mobility group 20A
Description: Exhibits protein heterodimerization activity. Involved in negative regulation of neuron differentiation; negative regulation of protein sumoylation; and negative regulation of transcription by RNA polymerase II. Localizes to the nucleus. Is expressed in several structures, including axial skeleton; early conceptus; genitourinary system; gut; and nervous system. Orthologous to human HMG20A (high mobility group 20A); INTERACTS WITH 17alpha-ethynylestradiol; 2,3,7,8-tetrachlorodibenzodioxine; benzo[a]pyrene.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: 1200004E06Rik; 5730490E10Rik; high mobility group protein 20A; HMG box-containing protein 20A; HMG domain-containing protein HMGX1; Hmgxb1; Ibraf; inhibitor of BRAF35
