CSNK1A1 + CSNK1A1L Recombinant Rabbit mAb (S-4407-18)

CK1α (casein kinase 1 isoform alpha) is a ubiquitously expressed, constitutively active serine/threonine kinase that docks to a conserved recognition motif (pSer/pThr-X-X-S/T) in hundreds of cytoplasmic, nuclear and membrane substrates, thereby governing Wnt/β-catenin signaling by phosphorylating β-catenin for β-TrCP-mediated degradation, synchronizing circadian rhythms through PER protein turnover, regulating DNA-damage checkpoints by modifying p53 and MDM2, driving hematopoietic stem-cell maintenance via AKT pathway modulation, and serving as an essential, druggable node whose loss-of-function triggers ribosomal stress and selective apoptosis in acute myeloid leukemia cells.
