Smoker's face describes the characteristic changes that happen to the faces of many people who smoke tobacco products. [1] [2] Smoking causes damage to the skin by depleting the skin of oxygen and nutrients. [3] The general appearance is of accelerated ageing of the face, with a characteristic pattern of facial wrinkling and sallow coloration.

In non-muscle cells, it is found by the actin filaments and at the adhesion sites. [1] The lattice like arrangement provides stability to the muscle contractile apparatus. [1] Specifically, it helps bind actin filaments to the cell membrane. [2] There is a binding site at each end of the rod and with bundles of actin filaments. [1]
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.
Actin, cytoplasmic 2, or gamma-actin is a protein that in humans is encoded by the ACTG1 gene. [5] Gamma-actin is widely expressed in cellular cytoskeletons of many tissues; in adult striated muscle cells, gamma-actin is localized to Z-discs and costamere structures, which are responsible for force transduction and transmission in muscle cells.
Actin beta (HUGO Gene Nomenclature Committee abbreviation ACTB/ACTB) is one of six different actin isoforms which have been identified in humans. This is one of the two nonmuscle cytoskeletal actins. Actins are highly conserved proteins [5] [6] that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of ...
Of all the fashion trends to make a comeback, cigarettes were an unlikely contender. After all, it’s 2024. A year when you can’t go 10 minutes on a night out without smelling the saccharine ...
Alpha-actinin-2 is a 103.8 kDa protein composed of 894 amino acids. [6] [7] Each molecule is rod-shaped (35 nm in length) and it homodimerizes in an anti-parallel fashion.. Each monomer has an N-terminal actin-binding region composed of two calponin homology domains, two C-terminal EF hand domains, and four tandem spectrin-like repeats form the rod domain in the central region of the molecule.
