Peptide Blocking:
Antibodies are typically supplied at 0.5mg/ml and peptides as a 100ug pellet. When peptides are reconstituted in 200ul water, the concentration will be 0.5mg/ml. To start, the best ratio would be 1:1 (which means molar excess of peptides relative to antibodies when identical volumes are mixed). Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature. It is best is to have two identical blots, to be incubated with equal amount of antibodies, but one with the antibodies pre-adsorbed to the peptide for 20min. Then incubate and develop the two blots in parallel.

NCBI Summary for ENPP1
This gene is a member of the ecto-nucleotide pyrophosphatase/phosphodiesterase (ENPP) family. The encoded protein is a type II transmembrane glycoprotein comprising two identical disulfide-bonded subunits. This protein has broad specificity and cleaves a variety of substrates, including phosphodiester bonds of nucleotides and nucleotide sugars and pyrophosphate bonds of nucleotides and nucleotide sugars. This protein may function to hydrolyze nucleoside 5' triphosphates to their corresponding monophosphates and may also hydrolyze diadenosine polyphosphates. Mutations in this gene have been associated with 'idiopathic' infantile arterial calcification, ossification of the posterior longitudinal ligament of the spine (OPLL), and insulin resistance.

UniProt Comments for ENPP1
Function: By generating PPi, plays a role in regulating pyrophosphate levels, and functions in bone mineralization and soft tissue calcification. PPi inhibits mineralization by binding to nascent hydroxyapatite (HA) crystals, thereby preventing further growth of these crystals. In vitro, has a broad specificity, hydrolyzing other nucleoside 5' triphosphates such as GTP, CTP, TTP and UTP to their corresponding monophosphates with release of pyrophosphate and diadenosine polyphosphates, and also 3',5'-cAMP to AMP. May also be involved in the regulation of the availability of nucleotide sugars in the endoplasmic reticulum and Golgi, and the regulation of purinergic signaling. Appears to modulate insulin sensitivity. Ref.10

Catalytic activity: Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.A dinucleotide + H2O = 2 mononucleotides.

Cofactor: Binds 2 divalent metal cations per subunit

By similarity.

Enzyme regulation: At low concentrations of ATP, a phosphorylated intermediate is formed which inhibits further hydrolysis.

Subunit structure: The secreted form is monomeric

By similarity. Homodimer; disulfide-linked. Interacts with INSR. Ref.10

Subcellular location: Cell membrane; Single-pass type II membrane protein. Basolateral cell membrane; Single-pass type II membrane protein. Secreted

By similarity. Note: The proteolytically processed form is secreted

By similarity. Targeted to the basolateral membrane in polarized epithelial cells and in hepatocytes, and to matrix vesicles in osteoblasts. In bile duct cells and cancer cells, located to the apical cytoplasmic side. Ref.11 Ref.12

Tissue specificity: Expressed in plasma cells and also in a number of non-lymphoid tissues, including the distal convoluted tubule of the kidney, chondrocytes and epididymis. Ref.9

Domain: The di-leucine motif is required for basolateral targeting in epithelial cells, and for targeting to matrix vesicles derived from mineralizing cells

By similarity.

Post-translational modification: Autophosphorylated as part of the catalytic cycle of phosphodiesterase/pyrophosphatase activity.N-glycosylated.It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.The interchain disulfide bonding resides in the transmembrane segment

By similarity.A secreted form is produced through cleavage at Lys-103 by intracellular processing

By similarity.

Involvement in disease: Ossification of the posterior longitudinal ligament of the spine (OPLL) [MIM:602475]: A calcification of the posterior longitudinal ligament of the spinal column, usually at the level of the cervical spine. Patients with OPLL frequently present with a severe myelopathy that can lead to tetraparesis.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.16Arterial calcification of infancy, generalized, 1 (GACI1) [MIM:208000]: A severe autosomal recessive disorder characterized by calcification of the internal elastic lamina of muscular arteries and stenosis due to myointimal proliferation.

Ref.17 Ref.18 Ref.20 Ref.24Diabetes mellitus, non-insulin-dependent (NIDDM) [MIM:125853]: A multifactorial disorder of glucose homeostasis caused by a lack of sensitivity to the body's own insulin. Affected individuals usually have an obese body habitus and manifestations of a metabolic syndrome characterized by diabetes, insulin resistance, hypertension and hypertriglyceridemia. The disease results in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.Note: Disease susceptibility is associated with variations affecting the gene represented in this entry.
