Cyclin A is especially interesting as it can activate two different cyclin-dependent kinases (Cdk2 and Cdk1) and function in both S-phase and mitosis [ 10 ]. Mammalian cells encode two A-type cyclins: cyclin A1 and cyclin A2.

WebCyclin A1 was shown to be expressed in testis and brain, as well as in several leukemic cell lines, and is thought to primarily function in the control of meiosis. This cyclin binds both Cdk1 and Cdk2 kinases, which give two distinct kinase activities, one appearing in S phase, the other in G2, and thus regulate separate functions in cell cycle. Webcyclin A (B-8) is recommended for detection of cyclin A and cyclin A1 of human origin by Western Blotting (starting dilution 1:100, dilution range 1:100-1:1000), … put in touch with 意味
