| pubmed-article:10094397 | pubmed:abstractText | Protein kinase CK2 forms complexes with some protein substrates what may be relevant for the physiological control of this protein kinase. In previous studies in rat liver cytosol we had detected that the trimeric form of eukaryotic translation initiation factor 2 (eIF-2) co-eluted with protein kinase CK2. We have now observed that the ratio between eIF-2 and cytosolic CK2 contents in testis, liver and brain is quite similar, being eIF-2 levels about 5-fold higher than those of CK2. Furthermore eIF-2 was present in liver samples immunoprecipitated with anti-CK2alpha/alpha' antibodies, confirming the existence of complexes containing both proteins. Nonetheless, these complexes would represent only a fraction of total cytosolic CK2 and eIF-2. We had also observed that rat liver membrane glycoproteins obtained through chromatography on wheat-germ lectin-Sepharose contain CK2 activity which copurifies with grp94/endoplasmin. We have now confirmed that this activity was due to the presence of protein kinase CK2 as evidenced by immunodetection with antibodies against CK2alpha/alpha'. The fractions enriched in grp94/endoplasmin and CK2 also contained another 55-kDa polypeptide (p55) phosphorylated by CK2 which has been identified as calreticulin by N-terminal sequencing. Calreticulin and grp94/endoplasmin could be partially resolved from CK2 by chromatography on heparin-agarose and almost completely on ConA-Sepharose. However, phosphorylation of immunoprecipitated grp94/endoplasmin was enhanced by its preincubation with purified CK2 prior to immunoprecipitation, what confirms the easy reassociation between these proteins. The association of protein kinase CK2 with eIF-2 and with grp94/endoplasmin may serve to locate the enzyme in the cellular machinery involved in protein synthesis and folding, and reinforces the possible involvement of CK2 in these processes. | lld:pubmed |
