  • 4 - POSTN Antibody (C-term) AP11962b
    Overlay histogram showing Hela cells stained with AP11962B(green line). The cells were fixed with 2% paraformaldehyde (10 min) and then permeabilized with 90% methanol for 10 min. The cells were then icubated in 2% bovine serum albumin to block non-specific protein-protein interactions followed by the antibody (AP11962B, 1:25 dilution) for 60 min at 37ºC. The secondary antibody used was Goat-Anti-Rabbit IgG, DyLight® 488 Conjugated Highly Cross-Adsorbed(1583138) at 1/200 dilution for 40 min at 37ºC. Isotype control antibody (blue line) was rabbit IgG1 (1μg/1x10^6 cells) used under the same conditions. Acquisition of >10, 000 events was performed.

Protein Information
Name POSTN
Synonyms OSF2
Function Enhances incorporation of BMP1 in the fibronectin matrix of connective tissues, and subsequent proteolytic activation of lysyl oxidase LOX (By similarity). Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization.
Cellular Location Golgi apparatus. Secreted, extracellular space, extracellular matrix. Note=Colocalizes with BMP1 in the Golgi.
Tissue Location Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus, thyroid tissue and breast. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor Overexpressed in breast cancers.
Research Areas
Periostin (POSTN) regulates tumor resistance to antiangiogenic therapy in glioma models.

BACKGROUND

POSTN binds to heparin. It induces cell attachment and spreading and plays a role in cell adhesion and may play a role in extracellular matrix mineralization.
