Disease

[ANGI_HUMAN] Defects in ANG are the cause of susceptibility to amyotrophic lateral sclerosis type 9 (ALS9) [MIM:611895]. ALS is a degenerative disorder of motor neurons in the cortex, brain stem and spinal cord. ALS is characterized by muscular weakness and atrophy.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Function

[ANGI_HUMAN] 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.^[7] ^[8]

Publication Abstract from PubMed

Human angiogenin is a member of the pancreatic ribonuclease superfamily that induces blood vessel formation. Its three-dimensional solution structure has been determined to high resolution by heteronuclear NMR spectroscopy. 30 structures were calculated, based on a total of 1441 assigned NOE correlations, 64 coupling constants and 50 hydrogen bonds. The backbone atomic rms difference from the mean coordinates is 0.067 +/- 0.012 nm and 0.13 nm from the previously determined crystal structure. The side-chain of Gln117 was found to obstruct the active site as observed in the crystal state. There was no evidence of an alternative open form of angiogenin, although two sets of chemical shifts were observed for some residues, mainly around the active site and in the C-terminal segment. The topology of the ribonucleolytic active site is described with a particular emphasis on the conformation and protonation of active-site His residues. The side-chain of His114 adopts two main conformations in solution. In contrast to pancreatic ribonuclease A, His13 was shown to be more basic than His114, with pKa values of 6.65 and 6.05 respectively. The His47 residue is located in an environment very resistant to protonation with a pKa lower than 4.
