Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables transcription coactivator activity. Involved in atrioventricular node cell development; myoblast differentiation; and positive regulation of myotube differentiation. Acts upstream of or within positive regulation of transcription of Notch receptor target. Located in nucleus. Is expressed in several structures, including branchial arch; genitourinary system; limb bud; neural ectoderm; and respiratory system epithelium. Orthologous to human MAML1 (mastermind like transcriptional coactivator 1).
