PA1-1062 detects APS from mouse samples.
PA1-1062 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~ 84 kDa protein corresponding to APS from recombinant mouse protein and 3T3L1 extracts.
The PA1-1062 immunogen is a synthetic peptide corresponding to residues E(605)A T L G R A R A V E N Q Y S(619) from mouse APS. This peptide (Cat. # PEP-246) can be used in neutralization and control experiments.
APS (adapter protein with Pleckstrin homology and Src homology 2 domains) a member of the Lnk family, is an adaptor protein that is involved in B-cell signaling, insulin signaling, cytoskeletal reorganization. It is tyrosine phosphorylated by JAK2, KIT and other kinases during B-cell receptor stimulation of many different cytokines, chemokines and leukokines. APS has been shown to inhibit the JAK-STAT pathway in collaboration with c-Cbl. It is located in the cytoplasm in pre-PDGF (platelet derived growth factor) stimulated cells and localizes to the plasma membrane and peripheral regions upon PDGF stimulation. This protein is expressed in B-cells and mast cells when detected in haematopoietic cell lines yet is also expressed in many different tissues including spleen, prostrate, testis, uterus, small intestine and skeletal muscle.
