Summary: This gene encodes an alpha-globulin protein with corticosteroid-binding properties. This is the major transport protein for glucorticoids and progestins in the blood of most vertebrates. The gene localizes to a chromosomal region containing several closely related serine protease inhibitors which may have evolved by duplication events. [provided by RefSeq, Jul 2008]
Expression: Biased expression in liver (RPKM 177.4), gall bladder (RPKM 27.4) and 1 other tissue See more

Here, we show that these issues can be addressed concurrently, using the serpin human a1-antichymotrypsin (ACT) as a model. We have introduced up to 15 amino acid substitutions into ACT, converting it into a surrogate corticosteroid-binding globulin (CBG), thereby creating a new binding globulin (NewBG).

Mass spectrometry confirmed the absence of neutrophil elastase (NE)-cleaved corticosteroid-binding globulin (CBG) in plasma in which ELISA values were highly discordant.

N-glycans at other sites also appear to protect CBG from neutrophil elastase or chymotrypsin.

We generated weighted polygenic risk score (PRS) based on 6 genome-wide significant SNPs (rs11621961, rs11629171, rs7161521, rs2749527, rs3762132, rs4900229). salivary cortisol increased in the high PRS group. It remained unchanged in low PRS group. These results were mainly driven by minor alleles of rs7161521 (SERPINA6) and rs4900229 (SERPINA1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
