The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 3.75 - 7.5 µg/ml.
機能Adapter protein involved in invadopodia and podosome formation, extracellular matrix degradation and invasiveness of some cancer cells. Binds matrix metalloproteinases (ADAMs), NADPH oxidases (NOXs) and phosphoinositides. Acts as an organizer protein that allows NOX1- or NOX3-dependent reactive oxygen species (ROS) generation and ROS localization. In association with ADAM12, mediates the neurotoxic effect of beta-amyloid peptide.
組織特異性Found in several cancer cell lines, particularly invasive breast carcinomas and melanomas.
配列類似性Belongs to the SH3PXD2 family. Contains 1 PX (phox homology) domain. Contains 5 SH3 domains.
ドメインThe PX domain is required for podosome localization because of its ability to bind phosphatidylinositol 3-phosphate (PtdIns(3)P) and phosphatidylinositol 3,4-biphosphate (PtdIns(3,4)P2) and, to a lesser extent, phosphatidylinositol 4-phosphate (PtdIns(4)P), phosphatidylinositol 5-biphosphate (PtdIns(5)P), and phosphatidylinositol 3,5-biphosphate (PtdIns(3,5)P2). Binds to the third intramolecular SH3 domain. The fifth SH3 domain mediates binding with ADAM12, ADAM15 and ADAM19.
翻訳後修飾Tyrosine phosphorylated by SRC. Phosphorylation plays a regulatory role in the protein localization. The intramolecular interaction of the PX domain with the third SH3 domain maintains the protein in the cytoplasm and phosphorylation disrupts this interaction, resulting in the redistribution of the protein from cytoplasm to the perimembrane region. Phosphorylated on serine upon DNA damage, probably by ATM or ATR.
細胞内局在Cytoplasm. Cell projection > podosome. Cytoplasmic in normal cells and localizes to podosomes in SRC-transformed cells.
