Product Description
Recombinant Biotinylated Human Siglec-5/CD170 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Glu17-Thr434.
Product Background
Group B Streptococcus (GBS) causes invasive infections in human newborns. the GBS β-protein attenuates innate immune responses by binding to sialic acid-binding immunoglobulin-like lectin 5 (Siglec-5), an inhibitory receptor on phagocytes.the polymorphism could influence the risk of prematurity among human fetuses of mothers colonized with GBS. This first functionally proven example of a paired receptor system in the Siglec family has multiple implications for regulation of host immunity.
