Purified anti-CDC2 Phospho (Tyr15) Antibody, CDC2, A21009D,BioLegend,613851

Cell division control protein 2 (CDC2) also known as Cyclin-dependent kinase 1 (CDK1) is a key regulatory kinase essential for cell growth, proliferation, cell cycle progression, and early embryonic development. It is responsible for driving cells through G2 phase into M phase. Prior to mitosis, CDC2, along with its binding partner cyclin B1, exists in an inactive state when phosphorylated on Thr14 and Tyr15 by PKMYT1 (MYT1) and WEE1. This B1-CDC2 complex is activated during G2 and early mitosis by CDC2-mediated dephosphorylation. During mitosis, CDC2 inhibits DNA re-replication and subsequent polyploidy and cell senescence through the sequestering of cyclin A2 and suppression of the formation of CDK2-cyclin A complexes. CDC2 can function as a substitute for other CDC family members and drive the progression of the cell cycle in the event of their loss. CDC2 functions as a positive regulator of global translation, protein synthesis, and genome stability and participates in DNA damage repair, checkpoint activation, and DNA replication fork progression. It is overexpressed in several cancers including liver, breast, and colorectal cancers and has been implicated in the promotion of tumorigenesis.
