Previous GeneCards Identifiers for VNN1 Gene
This gene encodes a member of the vanin family of proteins, which share extensive sequence similarity with each other, and also with biotinidase. The family includes secreted and membrane-associated proteins, a few of which have been reported to participate in hematopoietic cell trafficking. No biotinidase activity has been demonstrated for any of the vanin proteins, however, they possess pantetheinase activity, which may play a role in oxidative-stress response. This protein, like its mouse homolog, is likely a GPI-anchored cell surface molecule. The mouse protein is expressed by the perivascular thymic stromal cells and regulates migration of T-cell progenitors to the thymus. This gene lies in close proximity to, and in the same transcriptional orientation as, two other vanin genes on chromosome 6q23-q24. [provided by RefSeq, Feb 2009]
GeneCards Summary for VNN1 Gene
VNN1 (Vanin 1) is a Protein Coding gene. Among its related pathways are Pantothenate and CoA biosynthesis. GO annotations related to this gene include GPI anchor binding and pantetheine hydrolase activity. An important paralog of this gene is VNN2.
UniProtKB/Swiss-Prot for VNN1 Gene
Amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine.
