The antibody has been used for the detection of some phosphoserine containing proteins using immunoblotting and dot blotting.
Biochem/physiol Actions
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.
Protein phosphorylation and dephosphorylation are basic signaling mechanisms that modify protein function in eukaryotic cells. Phosphorylation is a rare posttranslational event in normal tissues, however, the abundance of phosphorylated cellular proteins increases several folds following various activation processes. The main amino acids that are phosphorylated are tyrosine, serine, or threonine (pTyr/pSer/pThr), each having specific kinases that phosphorylate them and specific phosphatases that dephosphorylate them. Mono and polyclonal antibodies directed against phosphorylated residues were generated and found useful as analytical and preparative tools by enabling the identification, quantification, and immunoaffinity isolation of phosphorylated cellular proteins.

Parkinson's disease is frequently associated with gastrointestinal symptoms, mostly represented by constipation and defecatory dysfunctions. This study examined the impact of central dopaminergic denervation, induced by injection of 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle, on distal colonic excitatory cholinergic

B-cell leukemia/lymphoma 2 (Bcl-2) blocks oxidant-induced apoptosis at least partly by stabilizing lysosomes. Here we report that phosphorylation of Bcl-2 may be required for these protective effects. J774 cells overexpressing wild-type Bcl-2 resist oxidant-induced lysosomal leak as well as apoptosis

We recently reported that the rat Nb2 T lymphoma cells expressed messenger RNAs (mRNAs) encoding both fibroblast growth factor-2 (FGF-2) and the FGF receptor, suggesting possible paracrine and/or autocrine roles for FGF-2 in lymphoma cell function. We have also shown
