UBE2Q2 was independently identified as a potential mitotic regulator (Banerjee et al. 2007), a gene expressed by the luminal epithelium of the endometrium at the embryo implantation site (UBCi; Melner et al. 2006), and as a gene overexpressed in head and neck tumors (LOC92912; Seghatoleslam et al. 2006). The gene discussed is UBE2Q2; the disease is head and neck neoplasm.
