Function

Protein binding:Selectively binds to other protein complexes non-covalently. Angiogenin promotes angiogenesis which is a stimulator of new blood vessels. While RNASE1 works to inhibit an endonuclease that cleaves phosphodiester bonds, and RNASE2 .

Disease

has a role in cancers and tumor growth. A mutation in 1a4y which results in increased activity of Ang could lead to tumor growth. Ang has also been theorized as a protector of the central nervous system and thus under-production of 1a4y may result in limited Ang and thus neurodegenerative diseases.

Relevance

Mutations in Angiogenin can result in drastic impacts on human health. As stated above, over or under production/activity can result in a broad range of diseases from cancers to neurodegenerative disorders.

Structural highlights

-The unusual non-globular structure of ribonuclease inhibitor, its solvent parallel and the conformational flexibility of the structure are used in the interaction. These structures make the ribonuclease inhibitor an effective binding protein. Ribonuclease inhibitor is encoded by the gene RNH1. Angiogenin- Encoded for by the ANG gene. It makes up the b and e chains of the 1a4y protein. It goes from residue numbers 25 to 147.
