CMA performs various specialized functions as well, depending on the specific protein undergoing degradation through this pathway and the cell type involved. For example, known CMA substrates include, MEF2D, a neuronal factor important for survival; Pax2, a transcription factor, important for the regulation growth of renal tubular cells; IκBα ...
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 lysosome. Alternative splicing of the gene produces three variants - LAMP-2A, LAMP-2B and LAMP-2C. [5] LAMP-2A is the receptor for chaperone-mediated autophagy ...
Autophagy (or autophagocytosis; from the Greek αὐτόφαγος, autóphagos, meaning "self-devouring" [1] and κύτος, kýtos, meaning "hollow") [2] is the natural, conserved degradation of the cell that removes unnecessary or dysfunctional components through a lysosome-dependent regulated mechanism. [3]
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.
My unsuspecting German shepherd mix, Daisy, helped me test out four different dog DNA kits to find the best one. All instructions were followed closely, with the exception of required swabbing times.
However the significance of this localization is not known. Mature yeast autophagosomes fuse directly with vacuoles or lysosomes and do not form amphisomes as in mammals. [8] In yeast autophagosome maturation, there are also other known players as Atg1, Atg13 and Atg17. Atg1 is a kinase upregulated upon induction of autophagy.
Structurally, the lamp proteins consist of two internally homologous lysosome-luminal domains separated by a proline-rich hinge region; at the C-terminal extremity there is a transmembrane region (TM) followed by a very short cytoplasmic tail (C). In each of the duplicated domains, there are two conserved disulfide bonds. This structure is ...
