|Application ||WB, IF, E|
|Other Accession||NP_001136, 4557313|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||16 kDa|
|Application Notes||ANG antibody can be used for detection of ANG by Western blot at 1 - 2 µg/mL. For immunofluorescence start at 20 µg/mL.|
|Target/Specificity||ANG; Two alternatively spliced transcript variants have been observed.|
|Reconstitution & Storage||ANG antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||ANG Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus. Stimulates ribosomal RNA synthesis including that containing the initiation site sequences of 45S rRNA. Cleaves tRNA within anticodon loops to produce tRNA-derived stress-induced fragments (tiRNAs) which inhibit protein synthesis and triggers the assembly of stress granules (SGs). Angiogenin induces vascularization of normal and malignant tissues. Angiogenic activity is regulated by interaction with RNH1 in vivo.|
|Cellular Location||Nucleus. Secreted, extracellular space, extracellular matrix, basement membrane. Nucleus, nucleolus. Note=Rapidly endocytosed by target cells and translocated to the nucleus where it accumulates in the nucleolus and binds to DNA|
|Tissue Location||Expressed predominantly in the liver. Also detected in endothelial cells and spinal cord neurons|

ANG Antibody: Angiogenin (ANG or ANG I) is important for the process of neovascularization and formation of new blood vessels. ANG is similar to pancreatic ribonuclease A and functions as a tRNA-specific ribonuclease that abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. It interacts with endothelial cell-surface actin and may cause changes in the cell cytoskeleton. ANG is thought to be involved in the development of solid tumors and its antagonists are capable of inhibiting tumor growth. Defects in ANG are the cause of susceptibility to amyotrophic lateral sclerosis type 9 (ALS9). Angiogenin is a genetic link between ALS and PD.
