SDC2 (Fibroglycan, Heparan sulfate proteoglycan core protein)

SDC2 (Syndecan-2) also known as SYND2, HSPG1, HSPG, and Fibroglycan, is a protein that in humans is encoded by the SDC2 gene. The protein encoded by this gene is a transmembrane (type I) heparan sulfate proteoglycan and is a member of the syndecan proteoglycan family. By Southern hybridization to a panel of human-mouse somatic cell hybrid DNA and by in situ hybridization, Marynen et al. (1989) showed that the heparan sulfate proteoglycan core protein maps to 8q22-q24. (Heparan sulfate proteoglycan of basement membrane appears to be encoded by a gene on human chromosome 1.Bobardt et al. (2003) demonstrated that syndecans, including SDC2, can function as in trans HIV receptors via binding of HIV-1 gp120 to the syndecan heparan sulfate chains. Flow cytometric analysis demonstrated SDC expression on endothelial cells. HIV bound to SDC on endothelial cell lines maintained its infectivity for at least 1 week, compared with less than 1 day for unbound virus. Bobardt et al. (2003) suggested that SDC-rich endothelial cells lining the vasculature can provide a microenvironment that boosts HIV replication in T cells.\n\nUniProt Number:\nP34741\n\nGene ID:\nSDC2\n\nApplications:\nSuitable for use in Western Blot and Immunohistochemistry (Paraffin).\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Handling:\nStore at -20?C for one year.
