Enables poly(A) binding activity. Predicted to be involved in cellular response to interferon-gamma; negative regulation of mRNA modification; and posttranscriptional regulation of gene expression. Predicted to act upstream of or within RNA splicing and mRNA processing. Located in cytoplasm. Part of histone pre-mRNA 3'end processing complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human SYNCRIP (synaptotagmin binding cytoplasmic RNA interacting protein). [provided by Alliance of Genome Resources, Apr 2022]
