Function
Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures (PubMed:8663200). In 0-1 hour embryos, forms a complex with me31B, cup, tral and pAbp which binds to various mRNAs including maternal mRNAs, and downregulates their expression during the maternal-to-zygotic transition (PubMed:28875934).
