The antibody detects endogenous levels of E2A only when phosphorylated at threonine 355.
Purification
Antibodies were purified by affinity-chromatography using epitope-specific peptide.
Immunogen
E2A (phospho Thr355) antibody was raised against a peptide sequence around phosphorylation site of threonine 355 (P-S-T (p)-P-V) derived from Human E2A .
E2A is a transcription factor that plays major roles in determining tissue-specific cell fate during embryogenesis, like muscle or early B-cell differentiation. Heterodimers between E2A and tissue-specific basic helix-loop-helix (bHLH) Dimers bind DNA on E-box motifs: 5'- CANNTG-3'. Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer. Deletions in E2A have been observed in a subset of pre-B-cell acute lymphoblastic leukemia (B-ALL) cases. Two alternatively spliced human isoforms have been described.
