A lysosome (/ ˈ l aɪ s ə ˌ s oʊ m /) is a single membrane-bound organelle found in many animal cells. [1] [2] They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins and its lumenal proteins.
Lysosomal-associated membrane protein 1 (LAMP-1) also known as lysosome-associated membrane glycoprotein 1 and CD107a (Cluster of Differentiation 107a), is a protein that in humans is encoded by the LAMP1 gene. The human LAMP1 gene is located on the long arm (q) of chromosome 13 at region 3, band 4 (13q34).
The degraded molecules need to be delivered to the cytoplasm; however, this will not be possible if the molecules are not hydrolyzed in the lysosome. [3] Autophagic intracellular digestion is processed in the cell, which means it digests the internal molecules. [3] Functions of autophagy
CD68 (also called gp110 or macrosialin) [5] is a heavily glycosylated integral membrane protein whose structure consists of a mucin-like domain followed by a proline-rich hinge; a single LAMP-like domain; a transmembrane region and a short cytoplasmic tail. CD molecules are leucocyte antigens on cell surfaces.

[3] [4] MCS are important in the function of the endoplasmic reticulum (ER), [5] since this is the major site of lipid synthesis within cells. [6] The ER makes close contact with many organelles, including mitochondria , Golgi , endosomes , lysosomes , peroxisomes , chloroplasts and the plasma membrane . [ 7 ]
Its protein, LAMP2, is one of the lysosome-associated membrane glycoproteins. The protein encoded by this gene is a member of a family of membrane glycoproteins. This glycoprotein provides selectins with carbohydrate ligands. It may play a role in tumor cell metastasis. It may also function in the protection, maintenance, and adhesion of the ...
Ragulator-Rag Complex, inactive. Ragulator-Rag Complex, active. The Ragulator-Rag complex is a regulator of lysosomal signalling and trafficking in eukaryotic cells, which plays an important role in regulating cell metabolism and growth in response to nutrient availability in the cell. [1]
