$319

Swiss-Prot No:

Swiss-Prot: P20042
NCBI Protein: NP_003899.2

Form of Antibody:

Supplied at 1.0mg/mL in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

Storage/Stability:

Immunogen:

Peptide sequence around phosphorylation site of serine 2 (M-S(p)-G-D-E) derived from Human eIF2β.

Purification:

Antibodies were produced by immunizing rabbits with synthetic peptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific peptide.

Specificity/Sensitivity:

The antibody detects endogenous levels of eIF2b only when phosphorylated at serine 2.

Applications:

WB

Background:

eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B.
