Serpin-derived peptide substrates for investigating the substrate specificity of human tissue kallikreins hK1 and hK2.
The third human tissue kallikrein to be identified, hK2, could be an alternate or complementary marker to kallikrein hK3 (prostate-specific antigen) for prostate diseases. Most of the hK2 in seminal plasma forms an inactive complex with protein C inhibitor (PCI), a serpin secreted by seminal vesicles. As serpin inhibitors behave as suicide substrates that are cleaved early in the interaction wi...
متن کاملDifferences in substrate and inhibitor sequence specificity of human, mouse and rat tissue kallikreins.
The kininogenase activities of mouse (mK1), rat (rK1) and human (hK1) tissue kallikreins were assayed with the bradykinin-containing synthetic peptides Abz-MTEMARRPPGFSPFRSVTVQNH2 (where Abz stands for o-aminobenzoyl) and Abz-MTSVIRRPPGFSPFRAPRV-NH2, which correspond to fragments Met374-Gln393 and Met375-Val393 of mouse and rat LMWKs (low-molecular-mass kininogens) with the addition of Abz. Bra...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولHuman tissue kallikreins: a road under construction.
BACKGROUND The human tissue kallikrein gene family, located at chromosome 19q13.4, is the largest contiguous family of proteases in the human genome. The locus encodes all 15 members of the family, 13 of which have been reported as potential biomarkers for several carcinomas and other non-neoplastic diseases. Kallikreins are expressed by a wide range of tissues and implicated in a number of phy...
