Protocols

Specificity / Sensitivity

ENPP1 Antibody (Human Specific) detects endogenous levels of total ENPP1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gln815 of human ENPP1. Antibodies were purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HepG2 and MDA-MB-231 cells using ENPP1 Antibody (Human Specific).

Background

Ectonucleotide pyrophosphatase-phosphodiesterase 1 (ENPP1) is a single-pass, type II transmembrane protein primarily involved in ATP hydrolysis at the plasma membrane. Targeting of ENPP1 to the basolateral cell surface relies on the presence of a carboxy-terminal di-leucine-based signal (1). ENPP1 plays important roles in bone mineralization and soft tissue calcification (2-5). Mutations in the corresponding ENPP1 gene cause generalized arterial calcification in infancy (GACI) and idiopathic infantile arterial calcification (IIAC) (6,7). ENPP1 inhibits insulin receptor function and overexpression of this enzyme causes insulin resistance and glucose intolerance in mice (8,9). Genetic variants of ENPP1 have been associated with obesity and type 2 diabetes (10-12).
