May be a signaling molecule that communicates mitogenic signals from the cytoplasm to the nucleus. Binds to the EGF and PDGF receptors. Binds to the elongation factor 1-alpha EF1A. Component of an import snRNP complex composed of KPNB1, SNUPN, SMN1 and ZNF259. Belongs to the ZPR1 family. Note: This description may include information from UniProtKB.
