Family eIF-3 subunit A family
Function
RNA-binding component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis. The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S pre-initiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation. The eIF-3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation, including cell cycling, differentiation and apoptosis, and uses different modes of RNA stem-loop binding to exert either translational activation or repression; FUNCTION: (Microbial infection) Essential for the initiation of translation on type-1 viral ribosomal entry sites (IRESs), like for HCV, PV, EV71 or BEV translation; FUNCTION: (Microbial infection) In case of FCV infection, plays a role in the ribosomal termination-reinitiation event leading to the translation of VP2.

In-vivo Model 3 to 5-week old female BALB/c athymic (NU/NU) nude mice were injected with 5 × 106 lung cancer cells with stably expression of relevant plasmids and randomly divided into indicated groups (five mice per group). To assess the in vivo effects of cycloleucine, the xenografted tumors had reached approximately 5 mm in diameter from mice and then these xenografted mice were feed with Vehicle or cycloleucine (25 mg/kg twice weekly) and tumor volume were measured every 3 day.
