This data was developed using ab157478, the same antibody clone in a different buffer formulation.ab157478 staining eIF2A in wild-type HAP1 cells (top panel) and EIF2A knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol for 5 minutes, permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1 hour. The cells were then incubated with ab157478 at 1μg/ml and ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1 hour with Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) secondary antibody at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

ab157478 was shown to recognize eIF2A when eIF2A knockout samples were used, along with additional cross-reactive bands. Wild-type and eIF2A knockout samples were subjected to SDS-PAGE. ab157478 and ab8245 (loading control to GAPDH) were diluted at 1/500 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.

Biological function summary
EIF2A impacts the translation mechanism by facilitating the binding of Met-tRNAi to the ribosome under particular conditions especially during stress responses where canonical eIF2 might be inhibited. It operates independently from the larger eIF2 complex which also includes eIF2β and eIF2γ subunits. This independent activity allows eIF2A to serve as a backup mechanism for translation initiation when the normal pathway is impaired.
Pathways
Translation regulation involves interaction with cellular stress pathways and the integrated stress response (ISR). eIF2A operates within pathways that respond to physiological stresses such as nutrient deprivation and oxidative stress which trigger alterations in protein synthesis rates. eIF2A is related to the eIF2 kinase which phosphorylates the α subunit of eIF2 leading to a general reduction in translation initiation under stress allowing selective translation of stress-response proteins.
