Rabbit anti-Human ENPP7 Polyclonal Antibody

Uniprot Id

Q6UWV6

Target Species

Human

Target Name

ENPP7

Target Full Name

Ectonucleotide pyrophosphatase/phosphodiesterase family member 7

Target Function

Choline-specific phosphodiesterase that hydrolyzes sphingomyelin releasing the ceramide and phosphocholine and therefore is involved in sphingomyelin digestion, ceramide formation, and fatty acid (FA) absorption in the gastrointestinal tract. Has also phospholipase C activity and can also cleave phosphocholine from palmitoyl lyso-phosphatidylcholine and platelet-activating factor (PAF) leading to its inactivation. Does not have nucleotide pyrophosphatase activity. May promote cholesterol absorption by affecting the levels of sphingomyelin derived from either diet or endogenous sources, in the intestinal lumen.

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein.

Target Protein Families

Nucleotide pyrophosphatase/phosphodiesterase family

Target Tissue Specificity

Detected in the colon (at protein level). Expressed in the duodenum, jejunum and liver and at low levels in the ileum. Expression was very low in the esophagus, stomach and colon.

Target Synonyms

ENPP7; UNQ3077/PRO9912; Ectonucleotide pyrophosphatase/phosphodiesterase family member 7; E-NPP 7; NPP-7; Alkaline sphingomyelin phosphodiesterase; Intestinal alkaline sphingomyelinase; Alk-SMase

Target Background

The protein encoded by this gene is an intestinal alkaline sphingomyelin phosphodiesterase that converts sphingomyelin to ceramide and phosphocholine. The encoded protein is anchored in the cell membrane, and it may function to protect the intestinal mucosa from inflammation and tumorigenesis. This protein is glycosylated and also exhibits lysophosphatidylcholine hydrolase activity.
