The molecular nature of tissue-specific Ags involved in MHC-restricted CTL responses is as yet undefined. To determine the specificity of these peptides, their function, and their possible relationship to allograft rejection, we have utilized human k

Enterokinase is a protease of the intestinal brush border that specifically cleaves the acidic propeptide from trypsinogen to yield active trypsin. This cleavage initiates a cascade of proteolytic reactions leading to the activation of many pancreati

The hepatitis C virus (HCV) H strain polyprotein is cleaved to produce at least nine distinct products: NH2-C-E1-E2-NS2-NS3-NS4A-NS4B-NS5A-NS5B-CO OH. In this report, a series of C-terminal truncations and fusion with a human c-myc epitope tag allowe

The hemostatic functions of human von Willebrand Factor (vWF) depend on the normal assembly of disulfide-linked multimers from approximately 250-kDa subunits. Subunits initially form dimers through disulfide bonds near the COOH terminus. Dimers then

The major histocompatibility complex class II molecules are composed of two polymorphic chains which, in cells normally expressing them, transiently associate with a third, nonpolymorphic molecule, the invariant chain (Ii). To determine differences i

It has been proposed that invariant chain (Ii), a nonpolymorphic, transmembrane glycoprotein found in noncovalent association with Ia molecules, may function to protect the Ia Ag-binding site from association with self-peptides during Ia synthesis. S

The A/Japan/57 influenza hemagglutin (HA) peptide HA 128-145, when bound by human histocompatibility leukocyte antigen-DRw11 cells, is recognized by the human CD4+ T cell clone V1. A rabbit antiserum has been raised against HA 128-145 which recognize

Type IV collagenase (gelatinase) readily cleaves denatured collagen into very small peptides. Large cyanogen bromide fragments (25 kDa) of type I collagen are degraded at the same rate as the complete alpha-chain. A number of the gelatinolytic cleava

Phosphorylation of the human interferon-gamma (IFN gamma) receptor was studied in three cell lines of distinct lineages using radiophosphate labeling techniques. Receptors from unstimulated Colo-205 displayed a low level of constitutive phosphorylati

Binding of peptides to MHC class II Ag generates ligands for TCR of Th lymphocytes. We have identified a novel class of peptides bound to MHC class II: mannose 6- phosphate (Man-6-P) containing glycopeptides from lysosomal enzymes. These species were
