VNN2 (vascular non-inflammatory molecule 2), also known as glycosyl- phosphatidyl inositol-anchored protein GPI-80, Vanin-2, and FOAP-4, is a GPI-anchored cell membrane protein belonging to the Vanin/BTD/VNN family of the carbon-nitrogen (CN) hydrolase family. The Vanin family includes secreted and membrane- associated proteins, a few of which have been reported to participate in hematopoietic cell trafficking. VNN2 shows high sequence similarity with other Vanin family members, and also with biotinidase. No biotinidase activity has been demonstrated for any of the vanin proteins.  VNN2 is an amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine. The pantetheinase activity of VNN2 may play a role in oxidative-stress response. VNN2 is widely expressed with higher expression in spleen and blood. VNN2 is involved in the thymus homing of bone marrow cells. It may regulate beta-2 integrin-mediated cell adhesion, migration and motility of neutrophil. Elevated VNN2 expression is associated with development and progression of thymoma.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
