The acute phase reactant serum amyloid A (SAA) is a polymorphic apolipoprotein encoded by a family of highly homologous and closely linked genes (summary by Steel et al., 1993). For background information on SAA, see SAA1 (104750).
Studying protein and cDNA, Whitehead et al. (1992) identified a member of the serum amyloid A protein superfamily, designated SAA4, as constitutive apolipoprotein of high density lipoprotein.
Watson et al. (1992) analyzed the derived protein structure of SAA4.
Watson et al. (1992) analyzed the structure of the SAA4 gene.
Steel et al. (1993) determined that the SAA4 gene shares the same 5-prime to 3-prime orientation and has the characteristic 4-exon structure of the other members of the SAA superfamily.
Steel et al. (1993) demonstrated that the SAA4 gene is located 9 kb downstream of the SAA2 gene (104751) on chromosome 11.
By fluorescence in situ hybridization using a cosmid probe carrying the SAA2 and SAA4 genes, Sellar et al. (1994) localized these genes to 11p15.1.
De Beer et al. (1996) found that in the mouse the Saa4 gene is linked to the serum amyloid A gene family on chromosome 7.
