Name :
Recombinant Human eIF3K Protein (His & GST Tag)
Biological Activity :
Background :
EIF3K is a member of the eIF3 subunit K family. It is a 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 4S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S preinitiation complex (43S PIC). It stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. EIF3K is universally expressed in human tissues. It is distributed both in nucleus and cytoplasm. EIF3K is the smallest subunit of eIF3 and it interacts with a number of other subunits of eIF3 and the 4S ribosomal subunit.
