 Myc-nick contains binding domains for histone acetyltransferases and for ubiquitin ligases.The functions of Myc-nick are currently under investigation, but this new Myc family member was found to regulate cell morphology, at least in part, by interacting with acetyl transferases to promote the acetylation of α-tubulin.Ectopic expression of Myc-nick accelerates the differentiation of committed myoblasts into muscle cells.
