PSG2
pregnancy specific beta-1-glycoprotein 2
The human pregnancy-specific glycoproteins (PSGs) are a family of proteins that are synthesized in large amounts by placental trophoblasts and released into the maternal circulation during pregnancy. Molecular cloning and analysis of several PSG genes has indicated that the PSGs form a subgroup of the carcinoembryonic antigen (CEA) gene family, which belongs to the immunoglobulin superfamily of genes. Members of the CEA family consist of a single N domain, with structural similarity to the immunoglobulin variable domains, followed by a variable number of immunoglobulin constant-like A and/or B domains. Most PSGs have an arg-gly-asp (RGD) motif, which has been shown to function as an adhesion recognition signal for several integrins, in the N-terminal domain (summary by Teglund et al., 1994 ). For additional general information about the PSG gene family, see PSG1 (MIM 176390).

AD Risk Scores
About AD Risk Scores
The TREAT-AD Center at Emory-Sage-SGC has developed a Target Risk Score (TRS) to objectively rank the potential involvement of specific genes in AD. The TRS is derived by summing two component risk scores, the Genetic Risk Score and the Multi-omic Risk Score, each of which is derived from a meta-analysis of multiple harmonized data sets. More information about the methodology used to define these risk scores is available here.
AD Risk Scores for PSG2
The TRS for PSG2, along with the component Genetic and Multi-omic Risk Scores, is shown here. The scores for PSG2 are superimposed on the genome-wide score distributions. If No Data is Currently Available is displayed for a score, that score was not calculated for PSG2.
Biological Domain Classification
About Biological Domains
A biological domain represents a standardized area of biology defined by a set of discrete, biologically coherent GO terms. The TREAT-AD Center at Emory-Sage-SGC has defined nineteen biological domains associated with AD, and objectively mapped genes to those biological domains using GO term annotations. More information about the methodology used to define AD biological domains, and to generate genome-wide biological domain mappings, is available here.
Biological Domains for PSG2
Select a biological domain on the left to see the list of GO terms that link PSG2 to it on the right. The percentage value displayed next to the currently selected biological domain indicates the proportion of PSG2's total unique GO terms that map to the biological domain. The ratio displayed on the right indicates how many of the biological domain's total GO terms PSG2 is annotated with.
