Abstract: crucial role that CK1α plays in regulating platelet production in both murine and human megakaryocytes (MKs).This work expands our current understanding of thrombopoiesis by placing CK1α at the crossroads of signaling, cytoskeletal regulation, and nuclear maturation in MKs.CK1α has garnered interest as a therapeutic target in hematologic malignancies, particularly in del(5q) myelodysplastic syndromes (MDS), where haploinsufficiency of CSNK1A1 sensitizes malignant clones to lenalidomide-induced degradation of CK1α.[4][5][6] However, the frequent thrombocytopenia observed in these patients with MDS has long lacked a unifying mechanistic explanation.The present study fills some of these knowledge gaps by demonstrating that CK1α deficiency directly impairs MK maturation, rather than simply suppressing MK proliferation.
