Amino acid length of protein:

464

Function of the normal/non-mutated protein:

This gene encodes a member of the lyase 1 family. The
            encoded protein forms a cytosolic homotetramer and primarily
            catalyzes the reversible hydrolytic cleavage of argininosuccinate
            into arginine and fumarate, an essential step in the liver in
            detoxifying ammonia via the urea cycle. 

Mutations implicated in causing the disorder:

Mutations in this gene
            result in the autosomal recessive disorder argininosuccinic
            aciduria, or argininosuccinic acid lyase deficiency. A
            nontranscribed pseudogene is also located on the long arm of
            chromosome 22. 

Impact of mutations on the structure and/or functioning of the protein:

Protein does not fold and interact with substrate properly
