EIF3K, also known as eukaryotic translation initiation factor 3 subunit K, belongs to the eIF3 subunit K family. It is the smallest subunit of eIF3 and it interacts with several other subunits of eIF3 and the 40S ribosomal subunit. This protein is conserved among high eukaryotes, including mammals, insects, and plants, and it is ubiquitously expressed in human tissues. It is distributed both in nucleus and cytoplasm and colocalizes with cyclin D3, a regulatory subunit of cyclin-dependent kinase 4 (Cdk4). Recombinant human EIF3K protein, fused to His-tag at N-terminal, was expressed in E. coli and purified by using conventional chromatography.
