Rabbit anti-Human ENTPD4 Polyclonal Antibody

Uniprot Id

Q9Y227

Target Species

Human

Target Name

ENTPD4

Target Full Name

Ectonucleoside triphosphate diphosphohydrolase 4

Target Function

Catalyzes the hydrolysis of nucleoside triphosphates and diphosphates in a calcium- or magnesium-dependent manner, with a preference for pyrimidines. Preferentially hydrolyzes UTP and TTP. AMP, ADP, ATP and UMP are not substrates. Preferentially activated by Ca(2+) over Mg(2+).; Has a broad substrate specificity with the ability of cleaving all nucleotide di- and triphosphates with the exception of adenosine di- and triphosphate (ADP and ATP). Preferentially hydrolyzes CTP, UDP, CDP, GTP and GDP. Can use either Ca(2+) or Mg(2+) equally.

Target Subcellular Location

[Isoform 1]: Cytoplasmic vesicle, autophagosome membrane; Multi-pass membrane protein. Lysosome membrane; Multi-pass membrane protein.; [Isoform 2]: Golgi apparatus membrane; Multi-pass membrane protein.

Target Protein Families

GDA1/CD39 NTPase family

Target Tissue Specificity

Ubiquitous. Highest expression in testis and lowest in bladder.

Target Synonyms

ENTPD4; KIAA0392; LALP70; LYSAL1; Ectonucleoside triphosphate diphosphohydrolase 4; NTPDase 4; Golgi UDPase; Lysosomal apyrase-like protein of 70 kDa; Uridine-diphosphatase; UDPase

Target Background

This gene encodes a member of the apyrase protein family. Apyrases are enzymes that catalyze the hydrolysis of nucleotide diphosphates and triphosphates in a calcium or magnesium-dependent manner. The encoded protein is an endo-apyrase and may play a role in salvaging nucleotides from lysosomes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and these isoforms may differ in divalent cation dependence and substrate specificity.
