Enables protein kinase binding activity. Acts upstream of or within regulation of receptor signaling pathway via JAK-STAT. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of elongator holoenzyme complex and transcription elongation factor complex. Is expressed in central nervous system; liver; and retina nuclear layer. Used to study autism spectrum disorder and intellectual disability. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability. Orthologous to human ELP2 (elongator acetyltransferase complex subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
