Gene Gene information from NCBI Gene database.
Entrez ID 891
Gene name Cyclin B1
Gene symbol CCNB1
Synonyms (NCBI Gene)
CCNB
Chromosome 5
Chromosome location 5q13.2
Summary The protein encoded by this gene is a regulatory protein involved in mitosis. The gene product complexes with p34(cdc2) to form the maturation-promoting factor (MPF). The encoded protein is necessary for proper control of the G2/M transition phase of the
