Small proteins are ubiquitous in all kingdoms of life. MicroProteins, initially characterized as small proteins with protein interaction domains that enable them to interact with larger multidomain proteins, frequently modulate the function of these proteins. The study of these small proteins has contributed to a greater comprehension of protein regulation. In addition to sequence homology, sequence-divergent small proteins have the potential to function as microProtein mimics, binding to structurally related proteins. Moreover, a multitude of other small proteins encoded by short open reading frames (sORFs) and peptides, derived from diverse sources such as long noncoding RNAs (lncRNAs) and miRNAs, contribute to a variety of biological processes. The potential of small proteins is evident, offering promising avenues for bioengineering that could revolutionize crop performance and reduce reliance on agrochemicals in future agriculture.

Background: Disruptions in proteostasis are recognized as key drivers in cerebro- and cardiovascular disease progression. Heat shock proteins (HSPs), essential for maintaining protein stability and cellular homeostasis, are pivotal in neuroperotection. Consequently, deepening the understanding the role of HSPs in ischemic stroke (IS) risk is crucial for identifying novel therapeutic targets and advancing neuroprotective strategies.

Background: Mucopolysaccharidosis (MPS) is a class of hereditary metabolic diseases that demonstrate itself by accumulating incompletely degraded glycosaminoglycans (GAGs). MPS are classified according to the kind(s) of stored GAG(s) and specific genetic/enzymatic defects. Despite the accumulation of the same type of GAG, two MPS diseases, Sanfilippo (MPS III) and Morquio (MPS IV), are further distinguished into subclasses based on different enzymes that are deficient.

Background: Psoriasis is a chronic and incurable skin inflammation driven by an abnormal immune response. Our study aims to investigate the potential of interferon-γ (IFN-γ) primed mesenchymal stem cells (IMSCs) in targeting T cells to attenuate psoriasis-like inflammation, and to elucidate the underlying molecular mechanism involved.
Methods: Mesenchymal stem cells (MSCs) were isolated from the umbilical cord and identified based on their surface markers.

It has become increasingly evident that the conformational distributions of intrinsically disordered proteins or regions are strongly dependent on their amino acid compositions and sequence. To facilitate a systematic investigation of these sequence-ensemble relationships, we selected a set of 16 naturally occurring intrinsically disordered regions of identical length but with large differences in amino acid composition, hydrophobicity, and charge patterning. We probed their conformational ensembles with single-molecule Förster resonance energy transfer (FRET), complemented by circular dichroism (CD) and nuclear magnetic resonance (NMR) spectroscopy as well as small-angle X-ray scattering (SAXS).

The synthesis of NR takes place on the surface of organelles known as rubber particles, which are found in latex - the cytoplasm of specialized cells known as laticifers. As well as the enzymes directly responsible for NR synthesis, the rubber particles also contain small rubber particle proteins (SRPPs), the most abundant of which are SRPP3, 4 and 5.
