Elevated aminopeptidase N affects sperm motility and early embryo development.

PLoS ONE, 2017
Aminopeptidase N (APN) is a naturally occurring ectopeptidase present in mammalian semen. Previous studies have demonstrated that APN adversely affects male fertility through the alteration of sperm motility.

Potential Activities of Freshwater Exo- and Endo-Acting Extracellular Peptidases in East Tennessee and the Pocono Mountains

Frontiers in Microbiology, 2018
Proteins constitute a particularly bioavailable subset of organic carbon and nitrogen in aquatic environments but must be hydrolyzed by extracellular enzymes prior to being metabolized by microorganisms.

The Effect of Different Species Aminopeptidase N Structure on the Activity Screening of Aminopeptidase N Inhibitor

Biological and Pharmaceutical Bulletin, 2010
Aminopeptidase N (APN) is a transmembrane metallopeptidase, which participates in the tumor progress such as proliferation, attachment, angiogenesis and tumor invasion. All of this makes APN as a good chemical therapeutic anti-tumor target. In the present study, we got a novel compound 16l which markedly inhibited the enzyme activity of porcine APN ...

Inactivation of interleukin-8 by aminopeptidase N (CD13) [PDF]

Journal of Leukocyte Biology, 1995
Abstract Aminopeptidase (APN) was found to degrade interleukin-8 (IL-8) and inactivate its chemotactic activity. The chemotactic activity of IL-8 was decreased by APN or neutrophil plasma membranes dose- and time-dependently. The chemotactic activity was not inactivated in the presence of bestatin or WM15 monoclonal antibody.

Antagonistic Ubiquitin Switching by USP7 and RNF40 Orchestrates KDM6A Homeostasis to License Coronavirus Susceptibility

Advanced Science, EarlyView.
We identify an antagonistic ubiquitin circuit that controls cellular permissiveness to multiple coronaviruses. The deubiquitinase USP7 stabilizes the epigenetic regulator KDM6A to upregulate viral receptors, while the E3 ligase RNF40 degrades KDM6A by catalyzing K6/K11‐ubiquitin chains of KDM6A for autophagic degradation.

Purification and functional characterisation of rhiminopeptidase A, a novel aminopeptidase from the venom of Bitis gabonica rhinoceros.

PLoS Neglected Tropical Diseases, 2010
BackgroundSnake bite is a major neglected public health issue within poor communities living in the rural areas of several countries throughout the world. An estimated 2.5 million people are bitten by snakes each year and the cost and lack of efficacy of

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Interspecies differences in membrane-associated protease activities of thyrocytes and their relevance for thyroid cancer studies

Journal of Experimental & Clinical Cancer Research, 2012
Background To understand the role of proteases involved in human thyroid cancer progression and tissue invasion, thyrocytes from other species could potentially be used provided their characteristics are similar.

A Renal Clearable Probe for In Vivo Monoamine Oxidase (MAO) Detection

Advanced Science, EarlyView.
A renal‐clearable Cy7‐based fluorogenic probe enables rapid and non‐invasive detection of monoamine oxidase (MAO) activity in vivo. Upon MAO‐mediated activation, the fluorescent product is efficiently excreted in urine, allowing direct quantification of enzyme overexpression.

RBD‐SD1 Nanoparticle Vaccines From DPP4‐Using Merbecoviruses Elicit a Cross‐Reactive Antibody Response but Limited Cross‐Protective Immunity

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles displaying RBD‐SD1 from MERS‐CoV, NL140422, and HKU4 elicited robust and cross‐reactive IgG responses in mice. Only MERS‐CoV RBD‐SD1 induced neutralizing antibodies against MERS‐CoV and protected human DPP4 mice from a MERS‐CoV challenge, indicating conserved serologic but limited cross‐neutralizing epitopes.
