Single-stranded DNA/RNA-binding protein with sequence specificity (By similarity). Binds G-rich elements in target mRNA coding sequences (By similarity). Prevents G-quadruplex structure formation in vitro, suggesting a role in supporting translation by resolving stable structures on mRNAs (By similarity). IRES trans-acting factor (ITAF) that can promote IRES-dependent translation of Myc mRNA (PubMed:24275942). Involved in the control of wing size by regulating Myc levels (PubMed:24275942). Associates with active polyribosomes. RNAi-mediated knockdown results in lethality before the pupal stage (PubMed:24275942). RNAi-mediated knockdown in the wing imaginal disks results in reduction of wing size associated with loss of patterning elements such as veins; this phenotype is reversed by Myc overexpression (PubMed:24275942).
