Multiple Domains in the Kv7.3 C-Terminus Can Regulate Localization to the Axon Initial Segment
The voltage-gated Kv7.2/Kv7.3 potassium channel is a critical regulator of neuronal excitability. It is strategically positioned at the axon initial segment (AIS) of neurons, where it effectively inhibits repetitive action potential firing.

miR-342-5p Decreases Ankyrin G Levels in Alzheimer’s Disease Transgenic Mouse Models
MicroRNA alterations and axonopathy have been reported in patients with Alzheimer’s disease (AD) and in AD mouse models. We now report that miR-342-5p is upregulated in APP/PS1, PS1ΔE9, and PS1-M146V transgenic AD mice, and that this upregulation is ...

Ankyrin-G coordinates intercalated disc signaling platform to regulate cardiac excitability in vivo. [PDF]
Rationale: Na v 1.5 ( SCN5A ) is the primary cardiac voltage-gated Na v channel. Na v 1.5 is critical for cardiac excitability and conduction, and human SCN5A

G-quadruplexes are specifically recognized and distinguished by selected designed ankyrin repeat proteins [PDF]
We introduce designed ankyrin repeat binding proteins (DARPins) as a novel class of highly specific and structure-selective DNA-binding proteins, which can be functionally expressed within all cells. Human telomere quadruplex was used as target to select specific binders with ribosome display.

Pathophysiological Roles of Abnormal Axon Initial Segments in Neurodevelopmental Disorders
The 20–60 μm axon initial segment (AIS) is proximally located at the interface between the axon and cell body. AIS has characteristic molecular and structural properties regulated by the crucial protein, ankyrin-G.

Cytoskeletal regulation of ENaC: the role of ankyrin G (892.28)
The epithelial sodium channel (ENaC) is a major determinant of sodium (Na+) and water balance in the kidney. The hormone aldosterone increases ENaC subunit translation and modifies expression of key regulators that alter ENaC function and membrane density.

Probing the druggability of the Notch1 ankyrin domain using a fragment-based approach
Notch signalling is a highly conserved pathway that is important in the developmental processes that control cell differentiation and cell fates. This canonical pathway involves binding of a transmembrane ligand in one cell to the extraceullular domain ...
