CDK14 (O94921) - Overview - Molecular Target Synopsis


CDK14, Cyclin-dependent kinase 14
Enzyme Classification
UniProt O94921

Also Known as CDK14_HUMAN, CDK14, KIAA0834, PFTK1

Serine/threonine-protein kinase involved in the control of the eukaryotic cell cycle, whose activity is controlled by an associated cyclin. Acts as a cell-cycle regulator of Wnt signaling pathway during G2/M phase by mediating the phosphorylation of LRP6 at 'Ser-1490', leading to the activation of the Wnt signaling pathway. Acts as a regulator of cell cycle progression and cell proliferation via its interaction with CCDN3. Phosphorylates RB1 in vitro, however the relevance of such result remains to be confirmed in vivo. May also play a role in meiosis, neuron differentiation and may indirectly act as a negative regulator of insulin-responsive glucose transport. Found in a complex with LRP6, CCNY and CAPRIN2 during G2/M stage; CAPRIN2 functions as a scaffold for the complex by binding to CCNY via its N terminus and to CDK14 via its C terminus (PubMed:27821587). Interacts with CCNY; CCNY mediates its recruitment to the plasma membrane and promotes phosphorylation of LRP6 (PubMed:20059949, PubMed:19524571). Interacts with CCDN3 and CDKN1A (PubMed:17517622). Interacts with SEPT8 (PubMed:12098780). Interacts with 14-3-3 proteina YWHAB, YWHAE, YWHAH and YWHAQ (PubMed:16775625).
