Novel functions of clathrin light chains: clathrin heavy chain trimerization is defective in light chain-deficient yeast.
Clathrin is a major coat protein involved in sorting and retention of proteins at the late Golgi and in endocytosis from the cell surface. The clathrin triskelion contains three heavy chains, which provide the structural backbone of the clathrin lattice and three light chains, which are thought to regulate the formation or disassembly of clathrin coats. To better understand the function of the ...
متن کاملKinesin light chain-independent function of the Kinesin heavy chain
In Drosophila, the asymmetries that specify the embryonic axes are established early during oogenesis in a process that requires the precise localisation of several transcripts (Riechmann and Ephrussi, 2001; van Eeden and St Johnston, 1999). The localisation of oskar mRNA to the posterior pole of the oocyte specifies where the pole plasm forms, and thus where the abdomen and the germ line will ...
متن کاملClathrin heavy chain: molecular cloning and complete primary structure.
We have deduced the 1675-amino acid sequence of rat clathrin heavy chain from cDNA clones and predict a protein of Mr 191,569. We have established the polarity of the heavy chain and assigned sequence positions to several structural landmarks of the clathrin leg. The terminal domain at the distal end of the clathrin leg is at the amino terminus of the heavy chain. It is connected to the distal ...
متن کاملClathrin light and heavy chain interface: alpha-helix binding superhelix loops via critical tryptophans.
Clathrin light chain subunits (LCa and LCb) contribute to regulation of coated vesicle formation to sort proteins during receptor-mediated endocytosis and organelle biogenesis. LC binding to clathrin heavy chain (HC) was characterized by genetic and structural approaches. The core interactions were mapped to HC residues 1267-1522 (out of 1675) and LCb residues 90-157 (out of 228), using yeast t...
متن کاملTransformation by Rous sarcoma virus induces clathrin heavy chain phosphorylation
We have shown that the heavy chain of clathrin is phosphorylated in chicken embryo fibroblast cells transformed by Rous sarcoma virus, but not in normal cells. Approximately 1 mol of phosphate is bound for every 5 mol of heavy chain in the maximally phosphorylated transformed cells. Two-thirds of the phosphate is on serine and one-third on tyrosine residues. Clathrin heavy chain is a substrate ...
