== Function ==
[https://www.uniprot.org/uniprot/ANG1_BOVIN ANG1_BOVIN] May function as a tRNA-specific ribonuclease that abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. Binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus. Angiogenin induces vascularization of normal and malignant tissues. Angiogenic activity is regulated by interaction with RNH1 in vivo. Has very low ribonuclease activity.

== Publication Abstract from PubMed ==
The three-dimensional structure of bovine angiogenin has been determined using two- and three-dimensional proton NMR spectroscopy. The solution structure is very close to that recently determined by X-ray diffraction analysis. This structure appears well defined, even if five loops and one helix exhibit greater flexibility. Analysis of the active site geometry confirms the position of the Glu-118 residue which obstructs the pyrimidine binding site. There is no experimental evidence of an unobstructed conformation of angiogenin in solution. In addition, it appears that the Glu-118 and Ser-119 residues and the cell receptor binding loop may play an important role in the differences of C-terminal fragment organization and ribonucleolytic activity observed between angiogenins and ribonuclease A.
