Predicted to enable protein serine/threonine kinase activity. Predicted to be involved in several processes, including endocytosis; positive regulation of canonical Wnt signaling pathway; and positive regulation of proteasomal ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within rhythmic process. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 36; autosomal recessive nonsyndromic deafness 7; invasive ductal carcinoma; and sensorineural hearing loss. Orthologous to several human genes including TPTEP2-CSNK1E (TPTEP2-CSNK1E readthrough).
