More than G1 or G2 arrest: useful starfish oocyte system for investigating skillful MAP kinase

Biol Cell. 2004 Apr;96(3):241-4. doi: 10.1016/j.biolcel.2004.01.001.


During the meiotic cycles in starfish oocytes, MAP kinase (MAPK) is involved in the meta-I arrest, the meiosis I to II transition, and the arrest at pronucleus stage (G1 and/or G2 phase). The eventual fate, either development or death, of mature eggs is also under the control of MAPK. Starfish oocytes are thus a useful model system to study multiple functions of skillful MAPK.
