Regulators of G protein signaling (RGS) proteins are important modulators of G protein-coupled receptors and, therefore, critical for cardiovascular functions. One family member, RGS5, has recently been identified as a key regulator of vascular remodeling and pericyte maturation in tumors. Here, we discuss a potential role for RGS5 and its relatives, RGS2 and 4, within the cardiovascular system. Insights into RGS5 signaling are likely to be highly significant for vascular pathologies such as hypertension, atherosclerosis, and angiogenesis.

Phytochromes are biliprotein photoreceptors found in bacteria, fungi, and plants. The soil bacterium Agrobacterium fabrum has two phytochromes, Agp1 and Agp2, which work together to control DNA transfer to plants and bacterial conjugation. Both phytochromes interact as homodimeric proteins.

Loz1 is a zinc-responsive transcription factor in fission yeast that maintains cellular zinc homeostasis by repressing the expression of genes required for zinc uptake in high zinc conditions. Previous deletion analysis of Loz1 found a region containing two tandem CH zinc-fingers and an upstream "accessory domain" rich in histidine, lysine, and arginine residues to be sufficient for zinc-dependent DNA binding and gene repression. Here we report unexpected biophysical properties of this pair of seemingly classical CH zinc fingers.

TBCK (TBC1 Domain-Containing Kinase) encodes a protein playing a role in actin organization and cell growth/proliferation via the mTOR signaling pathway. Deleterious biallelic TBCK variants cause Hypotonia, infantile, with psychomotor retardation and characteristic facies 3. We report on three affected sibs, also displaying cardiac malformations.

Abnormality of granulosa cells (GCs) is the critical cause of follicular atresia in premature ovarian failure (POF). RIPK3 is highly expressed in GCs derived from atretic follicles. We focus on uncovering how RIPK3 contributes to ovarian GC senescence.

Proteins' flexibility is a feature in communicating changes in cell signaling instigated by binding with secondary messengers, such as calcium ions, associated with the coordination of muscle contraction, neurotransmitter release, and gene expression. When binding with the disordered parts of a protein, calcium ions must balance their charge states with the shape of calcium-binding proteins and their versatile pool of partners depending on the circumstances they transmit. Accurately determining the ionic charges of those ions is essential for understanding their role in such processes.
