Biolegend, 626455, Alexa Fluor® 488 anti-PTEN Phospho (Ser380) Antibody, 25μg

PTEN is a tumor suppressor gene which encodes a phosphatase that preferentially dephosphorylates phosphoinositide substrates and thereby modulates cell cycle progression and cell survival. PTEN is an important negative regulator of the PI3K/AKT/mTOR signaling pathway by dephosphorylating PIP3. PTEN is commonly mutated in human cancer, hence, loss of expression/function of PTEN due to mutations have been observed in prostate cancer, glioblastoma, endometrial, lung and breast cancers. Other non-cancerous clinical disorders associated with PTEN mutation are Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, and proteus-like syndrome. PTEN is phosphorylated at several residues and some lead to increase in activity while others lead to loss of function and degradation. Specifically, phosphorylation at serine 380 residue by casein kinase 2 (CK2), leads to degradation of PTEN in the proteasome.

Structure: PTEN is a 403 amino acid protein with a predicted molecular weight of 55 kD. It has a tyrosine phosphatase domain and a C2 domain
Distribution: Cytoplasmic (Inner cellular membrane) and nuclear
Function: PTEN functions as a lipid and protein phosphatase. It is negatively regulated by phosphorylation at the C-terminal domain which leads to proteasomal degradation.
