Recombinant Human EIF3K Protein (Catalog#14553-H20B)
Preparation
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human EIF3K (rh EIF3K; Catalog#14553-H20B; Q9UBQ5; Ala2-Gln218). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

Immunofluorescence staining of Human EIF3K in Hela cells. Cells were fixed with 4% PFA, permeabilzed with 0.3% Triton X-100 in PBS, blocked with 10% serum, and incubated with mouse anti-Human EIF3K monoclonal antibody (1:60) at 4℃ overnight. Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-mouse IgG secondary antibody(green). Positive staining was localized to cytoplasm and nucleus.
eukaryotic translation initiation factor 3, subunit K
Description
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.
