這個基因是myc家族的一員，編碼一個具有基本螺旋-環-螺旋（bhlh）結構域的蛋白質。這種蛋白位于細胞核內，必須與另一種bhlh蛋白二聚以結合DNA。這種基因的擴增與多種腫瘤有關，尤其是神經母細胞瘤。該基因有多種編碼不同亞型的選擇性剪接轉錄變體。
This gene is a member of the MYC family and encodes a protein with a basic helix-loop-helix (bHLH) domain. This protein is located in the nucleus and must dimerize with another bHLH protein in order to bind DNA. Amplification of this gene is associated with a variety of tumors, most notably neuroblastomas. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.
