Enables RNA binding activity; ribonuclease activity; and ribosome binding activity. Involved in several processes, including cellular response to cytokine stimulus; negative regulation of gene expression; and negative regulation of intracellular signal transduction. Located in nucleus and rough endoplasmic reticulum. Is extrinsic component of endoplasmic reticulum membrane. Used to study primary biliary cholangitis. Human ortholog(s) of this gene implicated in hepatitis B. Orthologous to human ZC3H12A (zinc finger CCCH-type containing 12A). [provided by Alliance of Genome Resources, Apr 2022]
