VNN1 / Vanin-1抗体
Antibody Type : Rabbit Polyclonal Antibody ( Antibody Purification Platform )
抗体宿主 : Rabbit IgG
缓冲液 : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.
制备方法 : Produced in rabbits immunized with purified, recombinant Mouse VNN1 / Vanin-1 (rM VNN1 / Vanin-1; Catalog#50952-M08H; Q9Z0K8; Met1-Ser487). VNN1 / Vanin-1 specific IgG was purified by Mouse VNN1 / Vanin-1 affinity chromatography.
VNN1 / Vanin-1抗体 Background
Pantetheinase, also known as Pantetheine hydrolase, Vascular non-inflammatory molecule 1, Vanin-1, and VNN1, is a cell membrane protein which belongs to the CN hydrolase family and BTD/VNN subfamily. Vanin-1 contains one CN hydrolase domain. It is widely expressed with higher expression in spleen, kidney and blood. It is overexpressed in lesional psoriatic skin. Vanin-1 is also 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. Vanin-1 is an epithelial pantetheinase that provides cysteamine to tissue and regulates response to stress. Vanin-1 is expressed by enterocytes, and its absence limits intestinal epithelial cell production of proinflammatory signals. Vanin-1 regulates late adhesion steps of thymus homing under physiological, noninflammatory conditions. The early impact of vanin-1 deficiency on tumor induction was directly correlated to the amount of inflammation and subsequent epithelial proliferation rather than cell death rate. Vanin-1 molecule was shown to be involved in the control of thymus reconstitution following sublethal irradiation.
