Enables ATP binding activity and protein kinase activity. Involved in I-kappaB phosphorylation. Predicted to be located in cytoplasm. Predicted to be part of elongator holoenzyme complex. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in Riley-Day syndrome; asthma; medulloblastoma; and scoliosis. Orthologous to human ELP1 (elongator acetyltransferase complex subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
