Predicted to enable RNA binding activity and cyclin binding activity. Predicted to be involved in several processes, including IRES-dependent translational initiation of linear mRNA; entrainment of circadian clock by photoperiod; and regulation of translation. Predicted to act upstream of or within several processes, including insulin secretion involved in cellular response to glucose stimulus; regulation of gene expression; and regulation of insulin receptor signaling pathway. Predicted to be located in several cellular components, including cytoplasmic stress granule; nuclear lumen; and perinuclear region of cytoplasm. Orthologous to human RBM4 (RNA binding motif protein 4). [provided by Alliance of Genome Resources, Apr 2022]
