Airway proteolytic control of pneumococcal competence.

open access: yesPLoS Pathogens, 2023
Streptococcus pneumoniae is an opportunistic pathogen that colonizes the upper respiratory tract asymptomatically and, upon invasion, can lead to severe diseases including otitis media, sinusitis, meningitis, bacteremia, and pneumonia.

The human Transmembrane Protease Serine 2 is necessary for the production of Group 2 influenza A virus pseudotypes [PDF]

open access: yes, 2013
The monomer of influenza haemagglutinin is synthesized as a single polypeptide precursor that during maturation is cleaved by proteases into two active subunits. Other studies have demonstrated that the human Transmembrane Protease Serine 2 (TMPRSS2) can

New insights into the evolution of subtilisin-like serine protease genes in Pezizomycotina

open access: yesBMC Evolutionary Biology, 2010
Background Subtilisin-like serine proteases play an important role in pathogenic fungi during the penetration and colonization of their hosts. In this study, we perform an evolutionary analysis of the subtilisin-like serine protease genes of subphylum ...

SARS-CoV-2 entry into human airway organoids is serine protease-mediated and facilitated by the multibasic cleavage site

open access: yeseLife, 2021
Coronavirus entry is mediated by the spike protein that binds the receptor and mediates fusion after cleavage by host proteases. The proteases that mediate entry differ between cell lines, and it is currently unclear which proteases are relevant in vivo.

Independent Subtilases Expansions in Fungi Associated with Animals [PDF]

open access: yes, 2011
Many socially important fungi encode an elevated number of subtilisin-like serine proteases, which have been shown to be involved in fungal mutualisms with grasses and in parasitism of insects, nematodes, plants, other fungi, and mammalian skin.

T-SP1: a novel serine protease-like protein predominantly expressed in testis [PDF]

open access: yes, 2008
Here, we describe a novel member in the group of membrane-anchored chymotrypsin (S1)-like serine proteases, namely testis serine protease 1 (T-SP1), as it is principally expressed in testis tissue.

Interdependence of kallikrein-related peptidases in proteolytic networks [PDF]

open access: yes, 2010
Human kallikrein-related peptidases (KLKs) are 15 homologous serine proteases involved in several (patho)physiological processes, including cancer. Secreted as precursors, they are activated upon proteolytic release of a short propeptide. We searched for

Plant proteases [PDF]

open access: yes, 2020
Plant proteases are involved in most aspects of plant physiology and development, playing key roles in the generation of signaling molecules and as regulators of essential cellular processes such as cell division and metabolism.

Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD) [PDF]

open access: yes, 2004
Dendritic cells (DC) are known to present exogenous protein Ag effectively to T cells. In this study we sought to identify the proteases that DC employ during antigen processing.

Serine Proteases of Malaria Parasite Plasmodium falciparum: Potential as Antimalarial Drug Targets

open access: yesInterdisciplinary Perspectives on Infectious Diseases, 2014
Malaria is a major global parasitic disease and a cause of enormous mortality and morbidity. Widespread drug resistance against currently available antimalarials warrants the identification of novel drug targets and development of new drugs.
