Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Specificity / Sensitivity
Phospho-PTEN (Ser380/Thr382/383) (44A7) Rabbit mAb detects endogenous levels of PTEN only when phosphorylated at Ser380, Thr382 and Thr383.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Ser380, Thr382 and Thr383 of human PTEN.
Western blot analysis of extracts from HeLa and NIH/3T3 cells, using Phospho-PTEN (Ser380/Thr382/383) (44A7) Rabbit mAb. Membranes were either left untreated (-) or treated with (+) calf intestinal phosphatase (CIP) post Western transfer to verify phospho-specificity of the antibody.
PTEN (phosphatase and tensin homologue deleted on chromosome ten), also referred to as MMAC (mutated in multiple advanced cancers) phosphatase, is a tumor suppressor implicated in a wide variety of human cancers (1). PTEN encodes a 403 amino acid polypeptide originally described as a dual-specificity protein phosphatase (2). The main substrates of PTEN are inositol phospholipids generated by the activation of the phosphoinositide 3-kinase (PI3K) (3). PTEN is a major negative regulator of the PI3K/Akt signaling pathway (1,4,5). PTEN possesses a carboxy-terminal, noncatalytic regulatory domain with three phosphorylation sites (Ser380, Thr382, and Thr383) that regulate PTEN stability and may affect its biological activity (6,7). PTEN regulates p53 protein levels and activity (8) and is involved in G protein-coupled signaling during chemotaxis (9,10).
