Adapter protein that bridges CNOT7, a catalytic subunit of the CCR4-NOT complex, to EIF4E (By similarity). Facilitates maternal mRNAs decay during the maturation of oocytes and in the fertilized egg, and is required for the maternal-zygotic transition (MZT), zygotic cleavage and initiation of embryonic development (PubMed:32502391). Interacts with CNOT7 (PubMed:32502391). Interacts with EIF4E (By similarity). Interacts with CNOT8 (By similarity). Expressed in oocytes after germinal vesicle breakdown (PubMed:32502391). Expressed in testis and in olfactory epithelium. The disease is caused by variants affecting the gene represented in this entry. Belongs to the BTG family.
