Regulation of LAT trafficking to the plasma membrane
Rakhimbekova, Anastasia ; Cebecauer, Marek (advisor) ; Černý, Jan (referee)
Linker for activation of T cells is a palmitoylated transmembrane adaptor protein, which is expressed in most of immune cells, but not in immature and mature B cells. It plays an important role in T-cell activation and maturation. LAT is synthesized in the endoplasmic reticulum. Its sorting to the plasma membrane is controlled with various determinants, such as properties of the transmembrane domain and structural motifs in the intracellular part of the protein. Some of those determinants are important for posttranslational modifications, export from the Golgi apparatus and, probably, membrane microdomain targeting, while others interact with COPII machinery and mediate protein export from the endoplasmic reticulum or targeting to endosomes. Keywords: LAT, functional motifs, protein sorting, plasma membrane, Golgi apparatus
