|Protein Name||Eukaryotic translation initiation factor 2 subunit 1|
|Molecular Weight||36112 MW|
|Protein Function||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.|
|Sequence Similarities||Belongs to the eIF-2-alpha family.|
|Subcellular Localization||Cytoplasmic granule . The cytoplasmic granules are stress granules which are a dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress. Colocalizes with NANOS3 in the stress granules (By similarity). .|

1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
