General description
Monoclonal Anti-Phosphoserine (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.
Specificity
By ELISA and dot blot, the antibody reacts specifically with phosphorylated serine, both as free amino acid or conjugated to carriers such as BSA or KLH. No cross-reactivity is observed with non-phosphorylated serine, phosphothreonine, phosphotyrosine, AMP or ATP. This antibody has been used in immunoblotting for the localization of some phosphoserine-containing proteins. Certain proteins known to contain phosphorylated serine may not be recognized by this antibody due to steric hindrance of the recognition site.
Immunogen
phosphoserine conjugated to Keyhole Limpet Hemocyanin (KLH).
Application
Monoclonal Anti-Phosphoserine - Agarose may be used for the immunoprecipitation or immuno-affinity purification of serine phosphoproteins.The antibody may be used for the localization of some phosphoserine containing proteins using the immunoblotting method.
Biochem/physiol Actions
Reversible phosphorylation of proteins is an important post-translational modification that plays a regulatory role in the expression of most proteins in the cells. Reversible phosphorylation at multiple serine, tyrosine and threonine residues mediate numerous signalling pathways in both prokaryotic and Eukaryotic cells. Cellular proteins with phosphorylated serine increase many fold by the activation of serine kinases. Most mitogenic receptor systems such as EGF, PDGF, insulin receptors contain serine/threonine/tyrosine kinase domains that undergo autophosphorylation when receptors bind to the respective ligands. T cell antigen receptor complex or the receptors for some hemopoietic growth factors may stimulate these phosphorylation associated kinases,3 and cells transformed by viral oncogenes contain elevated levels of phosphorylated tyr/ser/thr.
Monoclonal Anti-Phosphoserine may be used for the identification of proteins containing phosphorylated serine both as the free amino acid or when conjugated to carriers such as BSA or KLH. It does not react with non-phosphorylated serine, phosphorylated tyrosine or threonine, AMP or ATP.

Regulation of microRNA (miR) biogenesis is complex and stringently controlled. Here, we identify the kinase GSK3β as an important modulator of miR biogenesis at Microprocessor level. Repression of GSK3β activity reduces Drosha activity toward pri-miRs, leading to accumulation of unprocessed

Reversible phosphorylation is the most widespread posttranslational protein modification, playing regulatory role in almost every aspect of cell life. The majority of protein phosphorylation research has been focused on serine, threonine and tyrosine that form acid-stable phosphomonoesters. However, protein histidine

Post-translational modifications such as glycosylation, phosphorylation, and sulfation, to name a few, serve many functions. As a result, the analysis of proteins and their post-translational modifications is particularly important for the study of diseases where multiple genes are known to be involved, such as heart disease, cancer and diabetes.
