Casein kinase 1, alpha 1 (CSNK1A1) regulates protein turnover via initiation of translation via EIF2 and participates in wnt signalling; a homologue CSKNK2A1 has been previously identified as an independent predictor of survival in squamous cell lung cancer [39]. This evidence concerns the gene CSNK1A1 and squamous cell lung carcinoma.
