转铁蛋白是一种单体血清糖蛋白(∼80,000 道尔顿),其通过受体介导的内吞作用结合到脊椎动物细胞表面的特定受体上,并递送多达 2 个 Fe3+ 原子 — 标记的 LDL 复合物是研究该现象的有用工具。携带铁的转铁蛋白进入核内体后,酸性环境即可促使铁离子从转铁蛋白–受体复合物中解离。铁释放后,脱铁转铁蛋白被回收至细胞膜中,其从受体中释放出来以结合更多的铁。因此,荧光转铁蛋白偶联物可以与荧光 LDL 配合使用,以区分溶菌体定向途径和内涵体回收通路。

这些实验通常是通过向培养细胞中加入荧光标记的转铁蛋白并通过显微镜进行分析。我们提供生物素化的转铁蛋白偶联物及超过 10 种荧光形式。

Abstract
Inhibition of caveolar uptake, SV40 infection, and beta1-integrin signaling by a nonnatural glycosphingolipid stereoisomer.
Authors:Singh RD, Holicky EL, Cheng ZJ, Kim SY, Wheatley CL, Marks DL, Bittman R, Pagano RE
Journal:J Cell Biol
PubMed ID:17371832
'Caveolar endocytosis is an important mechanism for the uptake of certain pathogens and toxins and also plays a role in the internalization of some plasma membrane (PM) lipids and proteins. However, the regulation of caveolar endocytosis is not well understood. We previously demonstrated that caveolar endocytosis and beta1-integrin signaling are ... More
The long and the short cycle. Alternative intracellular routes for trafficking of G-protein-coupled receptors.
Authors:Innamorati G, Le Gouill C, Balamotis M, Birnbaumer M
Journal:J Biol Chem
PubMed ID:11150299
'The C terminus of the human V2 vasopressin receptor contains multiple phosphorylation sites including a cluster of amino acids that when phosphorylated prevents the return of the internalized receptor to the cell surface. To identify the step where the recycling process was interrupted, the trafficking of the V2 receptor was ... More
Transfer of M2 muscarinic acetylcholine receptors to clathrin-derived early endosomes following clathrin-independent endocytosis.
Authors:Delaney KA, Murph MM, Brown LM, Radhakrishna H
Journal:J Biol Chem
PubMed ID:12093817
'Upon agonist stimulation, many G protein-coupled receptors such as beta(2)-adrenergic receptors are internalized via beta-arrestin- and clathrin-dependent mechanisms, whereas others, like M(2) muscarinic acetylcholine receptors (mAChRs), are internalized by clathrin- and arrestin-independent mechanisms. To gain further insight into the mechanisms that regulate M(2) mAChR endocytosis, we investigated the post-endocytic trafficking ... More
Identification and characterization of small molecules that inhibit intracellular toxin transport.
Authors:Saenz JB, Doggett TA, Haslam DB
Journal:Infect Immun
PubMed ID:17576758
'Shiga toxin (Stx), cholera toxin (Ctx), and the plant toxin ricin are among several toxins that reach their intracellular destinations via a complex route. Following endocytosis, these toxins travel in a retrograde direction through the endosomal system to the trans-Golgi network, Golgi apparatus, and endoplasmic reticulum (ER). There the toxins ... More
A burst of auxilin recruitment determines the onset of clathrin-coated vesicle uncoating.
Authors:Massol RH, Boll W, Griffin AM, Kirchhausen T
Journal:Proc Natl Acad Sci U S A
PubMed ID:16798879
'Clathrin-coated pits assemble on a membrane and pinch off as coated vesicles. The released vesicles then rapidly lose their clathrin coats in a process mediated by the ATPase Hsc70, recruited by auxilin, a J-domain-containing cofactor. How is the uncoating process regulated? We find that during coat assembly small and variable ... More
