The FLNA gene provides instructions for producing the protein filamin A, which helps build cells' extensive internal network of protein filaments called the cytoskeleton. The cytoskeleton gives structure to cells and allows them the flexibility to change shape. The cytoskeleton is also important for certain processes inside the cells, such as the movement of proteins within the cell and the breakdown of unneeded proteins. Filamin A primarily attaches (binds) to another protein called actin and helps it form the branching network of filaments that make up the cytoskeleton.

The FLNA gene provides instructions for producing the protein filamin A, which helps build cells' extensive internal network of protein filaments called the cytoskeleton. The cytoskeleton gives structure to cells and allows them the flexibility to change shape. The cytoskeleton is also important for certain processes inside the cells, such as the movement of proteins within the cell and the breakdown of unneeded proteins. Filamin A primarily attaches (binds) to another protein called actin and helps it form the branching network of filaments that make up the cytoskeleton.
Filamin A can also bind to many other proteins in the cell to carry out various functions, including the attachment of cells to one another (cell adhesion), cell movement (migration), determination of cell shape, the relay of signals within cells, and cell survival. These numerous functions involving filamin A have been found to play roles in regulating skeletal and brain development, the formation of heart tissue and blood vessels, blood clotting, skin elasticity, the maintenance of lung tissue, and the function of the digestive system.
Filamin A is also involved in the organisation of the extracellular matrix, which is the lattice of proteins and other molecules outside the cell. Filamin A binds to proteins called integrins, which span the cell membrane and anchor cells to the extracellular matrix. Through this binding, cells are correctly positioned and signals can be exchanged between the cell and the extracellular matrix.

Strep A
Strep A, or Group A streptococcus, is a common type of bacteria, which has been recognised as a cause of infections for many years. Most Group A streptococcus infections are mild, but in rare cases, these can cause serious illness and even death. Strep A, or Group A streptococcus (GAS), is a type of bacteria, with the scientific name Streptococcus.

Viral cough
Most coughs are caused by viral infections and usually soon go. This leaflet gives some tips on what to do and discusses which symptoms may indicate a more serious illness. Viral infections commonly affect the throat (larynx), the main airway ... See our separate editorial content called Coronavirus: what are asymptomatic and mild COVID-19? and.

Ovulation calculator
Open the ovulation calculator How does the ovulation calculator work. The ovulation calculator uses the date of your last period and your average cycle length to estimate your fertile window — the days when you're most likely to conceive. Ovulation usually happens about 14 days before your next period. By predicting this window, the tool helps.
