NCIt definition : Human CCNB2 wild-type allele is located in the vicinity of 15q22.2 and is approximately
20 kb in length. This allele, which encodes G2/mitotic-specific cyclin-B2 protein,
is involved in the regulation of the mitotic G2/M transition of the cell cycle. Aberrant
allelic expression, resulting from different mechanisms, could contribute through
an alteration of the spindle checkpoint, to the chromosomal instability observed in
cancer.;
