Comments
Comment typeDescription
FunctionBinds 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 (By similarity). {ECO:0000250}.
SimilarityBelongs to the pancreatic ribonuclease family. {ECO:0000305}.
Subcellular LocationSecreted, extracellular space, extracellular matrix, basement membrane {ECO:0000250}. Nucleus, nucleolus {ECO:0000250}. Note=Rapidly endocytosed by target cells and translocated to the nucleus where it accumulates in the nucleolus and binds to DNA. {ECO:0000250}.
SubunitInteracts with and forms a tight 1:1 complex with RNH1. Dimerization of two such complexes may occur (By similarity). {ECO:0000250}.
