The Role of Endoplasmic Reticulum Aminopeptidase 1 Biology in Immune Evasion by Tumours

Journal of Vaccines and Immunology, 2015
Expression of MHC I at the cell surface is essential for presenting peptides to circulating cytotoxic T cells. Interference with a number of components of the antigen processing machinery is an immune evasion mechanism that has been highlighted in a number of malignancies.

ERAP, KIR, and HLA-C Profile in Recurrent Implantation Failure

Frontiers in Immunology, 2021
The mother’s uterine immune system is dominated by uterine natural killer (NK) cells during the first trimester of pregnancy. These cells express killer cell immunoglobulin-like receptors (KIRs) of inhibitory or activating function. Invading extravillous

Relaxin‐2: Shaping the Proteomic Landscape of Skeletal Muscle Physiology, Glucose Trafficking, and Mitochondrial Function in Rat

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.
Cardioprotective hormone relaxin‐2 showed relevant effects on rat skeletal muscle by altering proteins linked to muscle function, regeneration, differentiation, mitochondrial function, glucose metabolism, and structural integrity and organization. Specifically, relaxin‐2 reduced the expression of 95 proteins, increased 32, and elicited unique proteins ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, Volume 73, Issue 9, Page 1278-1290, September 2026.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Post-transcriptional and epigenetic regulation of antigen processing machinery (APM) components and HLA-I in cervical cancers from Uighur women. [PDF]

PLoS ONE, 2012
Normal function of human leukocyte antigen class I (HLA-I) and antigen processing machinery (APM) proteins is required for T cell-mediated anti-tumor or antiviral immunity, whereas the tumor survival indicates a failure of the host in immune surveillance

Placental Leucine Aminopeptidase Efficiently Generates Mature Antigenic Peptides In Vitro but in Patterns Distinct from Endoplasmic Reticulum Aminopeptidase 1 [PDF]

The Journal of Immunology, 2010
Abstract All three members of the oxytocinase subfamily of M1 aminopeptidases, endoplasmic reticulum aminopeptidase 1 (ERAP1), ERAP2, and placental leucine aminopeptidase (PLAP), also known as insulin-regulated aminopeptidase, have been implicated in the generation of MHC class I-presented peptides.

Revisiting Enzyme Replacement Therapy for Aspartylglucosaminuria: Truncated Phosphotransferase Enhances Mannose‐6‐Phosphorylation and Cellular Uptake of Aspartylglucosaminidase

Journal of Inherited Metabolic Disease, Volume 49, Issue 5, September 2026.
ABSTRACT Aspartylglucosaminuria (AGU) is a lysosomal storage disorder caused by a deficiency of aspartylglucosaminidase (AGA), a hydrolase involved in the degradation of N‐glycosylated proteins. Currently, no approved therapies are available for AGU. Development of enzyme replacement therapy (ERT) for AGU has been hampered by the complex proteolytic ...

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 625-638, September 2026.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

The Mechanobiology of Adipocyte Hypertrophy: Cytoskeletal Remodelling as a Driver of Insulin Resistance in Obesity

Cell Biochemistry and Function, Volume 44, Issue 8, August 2026.
ABSTRACT Adipocyte hypertrophy poses an important mechanical challenge—adipocytes can increase in volume up to a thousand‐fold while still maintaining their structural integrity. Although lipid metabolism is well studied, little is known about the cytoskeletal adaptations that are required to accommodate this expansion and the resulting pathological ...
