The structure of lamins is composed of three units that are common among intermediate filaments: a central α-helical rod domain containing heptad repeats surrounded by globular N and C-terminal domains.
The nuclear lamina: a dense fiber network inside the nucleus of cells. [6] The lamina affixa: a layer of epithelium growing on the surface of the thalamus. The lamina of Drosophila is the most peripheral neuropil of the insect visual system. Lamina cribrosa with two different meanings. Osseous spiral lamina, a feature of the bony canal of the ...
Some theorize that the lamina lucida is an artifact created when preparing the tissue, and that the lamina lucida is therefore equal to the lamina densa in vivo. [7] The term "basal lamina" is usually used with electron microscopy, while the term "basement membrane" is usually used with light microscopy. Examples of basement membranes include:
Mapping of the LamB1 5'-untranslated region (UTR) revealed the minimal LamB1 IRES motif between -293 and -1 upstream of the start codon. RNA affinity purification demonstrated that the La protein interacts with the LamB1 IRES. This interaction and its regulation during EMT were confirmed by ribonucleoprotein immunoprecipitation.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Lamina VII: intermediomedial nucleus, intermediolateral nucleus, posterior thoracic nucleus in the thoracic and upper lumbar region [6] Lamina X: an area of grey matter – the grey commissure surrounding the central canal. This region also serves to connect the anterior and posterior grey columns. [3] Rexed never described this as lamina X but ...
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
The nuclear lamina is a dense (~30 to 100 nm thick) fibrillar network inside the nucleus of eukaryote cells. It is composed of intermediate filaments and membrane associated proteins . Besides providing mechanical support, the nuclear lamina regulates important cellular events such as DNA replication and cell division .
