Experiment Name: Coimmunoprecipitation of endogenous RGS2 with endogenous eIF2B?.

Experiment Background: RGS2 was capable of interfering with the eIF2-eIF2B GTPase cycle, which is a requisite step for the initiation of mRNA translation.

Experiment Steps: 1. Treat UMR-106 osteoblastlike osteosarcoma cells for for 3 h with 100 ?M forskolin to induce RGS2 expression.
2. Incubate forskolin-treated cell lysates (1 mg total protein) with protein A/G agarose beads either without (lanes 1 and 3) or with (lanes 2 and 4) anti eIF2B? antibody.
3. Wash Protein A/G agarose beads extensively and remove the bound protein by heating
4. Perfrom SDSPAGE.
5. Transfer SDS-PAGE gel to PVDF membrane.
6. Probe membrane with anti-RGS2 antibody.
7. Reprobe using the same eIF2B? antibody.
8. visualize blots by chemiluminescence.
Function: Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. May play a role in leukemogenesis.

Tissue Specificity: Expressed in acute myelogenous leukemia (AML) and in acute lymphoblastic leukemia (ALL).

Ptm: Phosphorylated by protein kinase C.

Similarity: Contains 1 RGS domain. [1] Riddle,E.L., Rana,B.K., Murthy,K.K., Rao,F., Eskin,E., O\'Connor,D.T. and Insel,P.A.
