SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily E member 1-related is a protein that in humans is encoded by the HMG20B gene.^[5]^[6]

HMG20B is a high-mobility group (HMG) DNA binding protein. HMG20B contains a carboxy terminal region that is essential for cytokinesis since it regulates cell cycle progression from the G2 phase into mitosis^[7] This carboxy terminal region of HMG20B interacts with the tumor suppressor protein BRCA2. A particular mutation in this region of the HMG20B gene is associated with lung cancer. This mutation interferes with the association of the HMG20B and BRCA2 proteins.^[7]
