Last Modified 2014-10-13 [Report errors or provide feedback]
Gene Symbol SAA1
Protein Name serum amyloid A1
Synonyms PIG4; SAA; SAA2; TP53I4;
Species Homo sapiens
Ensembl Protein ENSP00000348918
InnateDB Gene IDBG-34659 (SAA1)
Protein Structure
UniProt Annotation
Function Major acute phase protein.
Subcellular Localization Secreted {ECO:0000269PubMed:7115671}.
Disease Associations Note=Reactive, secondary amyloidosis is characterized by the extracellular accumulation in various tissues of the SAA1 protein. These deposits are highly insoluble and resistant to proteolysis; they disrupt tissue structure and compromise function. {ECO:0000269PubMed:1463770}.Note=Elevated serum SAA1 protein levels may be associated with lung cancer. {ECO:0000269PubMed:1463770}.
Tissue Specificity Expressed by the liver; secreted in plasma (at protein level). {ECO:0000269PubMed:12973732, ECO:0000269PubMed:4816450, ECO:0000269PubMed:7115671}.
