Crystal Structure of Human Cyclophilin A Bound to the Amino-Terminal Domain of HIV-1 Capsid
The HIV-1 capsid protein forms the conical core structure at the center of the mature virion. Capsid also binds the human peptidyl prolyl isomerase, cyclophilin A, thereby packaging the enzyme into the virion. Cyclophilin A subsequently performs an essential function in HIV-1 replication, possibly helping to disassemble the capsid core upon infection. We report the 2.36 A crystal structure of t...
متن کاملStructure of the GAT domain of human GGA1: a syntaxin amino-terminal domain fold in an endosomal trafficking adaptor.
The Golgi-associated, gamma-adaptin homologous, ADP-ribosylation factor (ARF)-interacting proteins (GGAs) are adaptors that sort receptors from the trans-Golgi network into the endosomallysosomal pathway. The GGAs and TOM1 (GAT) domains of the GGAs are responsible for their ARF-dependent localization. The 2.4-A crystal structure of the GAT domain of human GGA1 reveals a three-helix bundle, with...
متن کاملAmino terminal tyrosine phosphorylation of human MIXL1
Seven members of the Mix family of paired-type homeoproteins regulate mesoderm/endoderm differentiation in amphibians. In mammals, the MIXL1 (Mix. 1 homeobox [Xenopus laevis]-like gene 1) gene is the sole representative of this family. Unlike the amphibian Mix genes that encode an open reading frame of >300 amino acids, mammalian MIXL1 encodes a smaller protein (approximately 230aa). However, m...
متن کاملHuman FMRP contains an integral tandem Agenet (Tudor) and KH motif in the amino terminal domain.
Fragile X syndrome, a common cause of intellectual disability and autism, is due to mutational silencing of the FMR1 gene leading to the absence of its gene product, fragile X mental retardation protein (FMRP). FMRP is a selective RNA binding protein owing to two central K-homology domains and a C-terminal arginine-glycine-glycine (RGG) box. However, several properties of the FMRP amino terminu...
متن کاملAnchoring fibrils contain the carboxyl-terminal globular domain of type VII procollagen, but lack the amino-terminal globular domain.
Type VII procollagen has been characterized as a product of epithelial cell lines. As secreted, it contains a large triple-helical domain terminated by a multi-globular-domained carboxyl terminus (NC-1), and a smaller amino-terminal globule (NC-2). The triple helix and the NC-1 domain have previously been identified in anchoring fibril-containing tissues by biochemical and immunochemical means,...
