Enables RNA stem-loop binding activity and chromatin binding activity. Involved in cellular response to lipopolysaccharide; positive regulation of T-helper 17 type immune response; and positive regulation of cytokine production. Acts upstream of or within chondrocyte differentiation; positive regulation of histone acetylation; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including ear; heart; hemolymphoid system; nervous system; and neural retina. Orthologous to human ARID5A (AT-rich interaction domain 5A). [provided by Alliance of Genome Resources, Apr 2022]
