Tissue Damage in Rheumatoid Arthritis is Genetically linked to Low Peptidylglycine Alpha‐Amidating Monooxygenase Activity in Synovial Fibroblasts

Arthritis &Rheumatology, Accepted Article.
Objectives Both susceptibility to, and severity of, rheumatoid arthritis (RA) is associated with the rs26232 C allele. Our primary aim was to identify the biological mechanism underlying this association. Methods Expression of surrounding genes was compared between rs26232 genotypes.

The Sexual Dimorphism in Rectum and Protein Digestion Pathway Influence Sex Pheromone Synthesis in Male Bactrocera Dorsalis

Advanced Science
Sexual dimorphism is a crucial aspect of mating and reproduction in many animals, yet the molecular mechanisms remain unclear. In Bactrocera dorsalis, sex pheromones trimethylpyrazine (TMP) and tetramethylpyrazine (TTMP) are specifically synthesized by ...

Multimodal Chromatography in the Downstream Processing of mAb‐Based Products: Mechanisms, Strategies, and Applications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Multimodal chromatography has emerged as a powerful tool for the purification of monoclonal antibodies (mAbs) and their derivatives—including antibody fragments (Fabs), Fc‐fusions, bispecific (BsAb), and antibody–drug conjugates (ADCs)—offering enhanced selectivity through the integration of ionic, hydrophobic, hydrogen‐bonding, and π–π ...

Digestive proteolytic activity in Apodiphus amygdali Germar (Hemiptera: Pentatomidae): effect of endogenous inhibitors

Journal of Entomological and Acarological Research, 2014
The digestive proteolytic profile of Apodiphus amygdali was determined by using several substrates and specific inhibitors. Analysis of optimal pH and temperature showed the highest enzymatic activity at the pH range of 6-7 and temperature of 40°C when ...

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Basic and Non‐Basic Substrates of Carboxypeptidase B [PDF]

European Journal of Biochemistry, 1973
The kinetics of porcine‐carboxypeptidase‐B‐catalyzed hydrolysis of several N‐blocked peptides that differ in size and in C‐terminal amino acid were examined. The data demonstrate different kinetic behaviour of carboxypeptidase‐B‐catalyzed hydrolysis of basic and non‐basic substrates.

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

Cytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

C‐Terminal Tail Elongation Adds a New Dimension to the Tubulin Code

Cytoskeleton, EarlyView.
ABSTRACT Tubulin C‐terminal tails undergo diverse post‐translational modifications that regulate microtubule interactions with motors and severing enzymes. TTLL11, a member of the tubulin tyrosine ligase‐like (TTLL) family, uniquely catalyzes glutamate addition to the terminal α‐carboxyl group of both α‐ and β‐primary tubulin tails.

Inhibition of plasminogen activation by apo(a): role of carboxyl-terminal lysines and identification of inhibitory domains in apo(a)[S]

Journal of Lipid Research, 2014
Apo(a), the distinguishing protein component of lipoprotein(a) [Lp(a)], exhibits sequence similarity to plasminogen and can inhibit binding of plasminogen to cell surfaces. Plasmin generated on the surface of vascular cells plays a role in cell migration

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...
