Cutting edge: C1q binds deoxyribose and heparan sulfate through neighboring sites of its recognition domain.
C1q, the recognition subunit of the C1 complex of complement, is an archetypal pattern recognition molecule with the striking ability to sense a wide variety of targets, including a number of altered self-motifs. The recognition properties of its globular domain were further deciphered by means of x-ray crystallography using deoxy-D-ribose and heparan sulfate as ligands. Highly specific recogni...
متن کاملAgouti-related peptide plays a critical role in leptin's effects on female puberty and reproduction.
Deficient leptin signaling causes infertility via reduced activity of GnRH neurons, causing a hypogonadal state in both rodents and humans. Because GnRH neurons do not express leptin receptors, leptin's effect on GnRH neurons must be indirect. Neurons within the hypothalamic arcuate nucleus that coexpress AGRP and NPY are considered to be important intermediate neurons involved in leptin regula...
متن کاملOpticin binds to heparan and chondroitin sulfate proteoglycans.
PURPOSE The extracellular matrix glycoprotein opticin is a small leucine-rich repeat proteoglycan/protein family member that was discovered associated with vitreous humor collagen fibrils. Opticin is present throughout the vitreous, but is particularly concentrated at the internal limiting lamina, where it colocalizes with type XVIII collagen. The present study investigated whether opticin inte...
متن کاملMapping critical biological motifs and biosynthetic pathways of heparan sulfate.
Heparan sulfate (HS) interacts with numerous proteins at the cell surface and orchestrates myriad biological events. Unraveling the mechanisms of these events at the molecular level calls for the structural analysis of these negatively charged and highly heterogeneous biopolymers. However, HS is often available only in small quantities, and the task of structural analysis necessitates the use o...
متن کاملHeparan sulfate expression in polarized epithelial cells: the apical sorting of glypican (GPI-anchored proteoglycan) is inversely related to its heparan sulfate content
Several processes that occur in the luminal compartments of the tissues are modulated by heparin-like polysaccharides. To identify proteins responsible for the expression of heparan sulfate at the apex of polarized cells, we investigated the polarity of the expression of the cell surface heparan sulfate proteoglycans in CaCo-2 cells. Domain-specific biotinylation of the apical and basolateral m...
