CSNK2A1 and autism spectrum disorder: Casein kinase II subunit alpha (CSNK2A1), encoded by theCSNK2A1 gene, is a catalytic subunit of the serine/threonine kinase, casein kinase 2; important for cell cycle progression, apoptosis, transcription and viral replication.1–5 Relevant to the etiology of many diseases, including the identification of two missense mutations in theCSNK2A1 gene associated with autism spectrum disorder, CSNK2A1 is emerging as a promising biomarker and therapeutic target.1,6–17 High-performing antibodies would enable data reproducibility and reliable research findings.
