The different mRNA isoforms of the mouse Sox17 gene were isolated from adult mouse testis cDNAs. One form (referred to as form Sox17) encodes an Sry-related protein of 419 amino acids containing a single high mobility group box near the NH2-terminus, while the other form (referred to as form t-Sox17) shows a unique mRNA isoform of the Sox17 gene with a(More)
Microarray analysis of oligodendrocyte lineage cells purified by fluorescence-activated cell sorting (FACS) from 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)-enhanced green fluorescent protein (EGFP) transgenic mice revealed Sox17 (SRY-box containing gene 17) gene expression to be coordinately regulated with that of four myelin genes during postnatal(More)
The matrix metalloproteinase (MMP) family, comprising more than 20 isoforms, modulates the extracellular milieu by degrading extracellular matrix (ECM) proteins. Because MMP is one of the few groups of proteinases capable of hydrolysing insoluble fibrillar proteins, they are likely to play crucial roles in regulating both normal and pathophysiological(More)
The Ras target AF-6 has been shown to serve as one of the peripheral components of cell-cell adhesions, and is thought to participate in cell-cell adhesion regulation downstream of Ras. We here purified an AF-6-interacting protein with a molecular mass of approximately 220 kD (p220) to investigate the function of AF-6 at cell-cell adhesions. The peptide(More)
The Drosophila fat facets and canoe genes regulate non-neural cell fate decisions during ommatidium formation. We have shown previously that the FAM (fat facets in mouse) de-ubiquitinating enzyme regulates the function of AF-6, (mammalian canoe homologue), in the MDCK epithelial cell line (Taya et al., 1998. The Ras target AF-6 is a substrate of the fam(More)
FAM is a developmentally regulated substrate-specific deubiquitylating enzyme. It binds the cell adhesion and signalling molecules beta-catenin and AF-6 in vitro, and stabilises both in mammalian cell culture. To determine if FAM is required at the earliest stages of mouse development we examined its expression and function in preimplantation mouse embryos.(More)
We report the cloning and expression pattern of a novel Ste20-type kinase gene, NIK-related kinase (Nrk), located on the mouse X chromosome. The full-length Nrk cDNA encodes a 1455-amino-acid polypeptide characterized by a N-terminal Ste20-type catalytic domain and a C-terminal regulatory domain characteristic of the group I GCK subfamily. The overall(More)
Mfge8 (milk fat globule-EGF-factor 8) encodes a soluble integrin-binding protein containing two Notch-like EGF domains and two discoidin domains. It mediates cell-to-cell interaction by binding to integrin alphavbeta3 via the RGD motif of its second EGF domain. Mfge8 was first expressed at 10.0 dpc in cells of the coelomic epithelium covering the(More)
A membrane-surface glycoprotein, RANDAM-2, is one of the neuronal cell lineage-specific antigens involved in the neuronal differentiation of P19 embryonic carcinoma (EC) cells and the mouse central nervous system (CNS). Complementary DNA cloning of RANDAM-2 indicated that its nucleotide sequence completely matched that of PA2.26 antigen, a sialomucin-like(More)
During the Drosophila oogenic processes, Fat facets (Faf), an ubiquitin-specific protease essential for normal development of oocyte and eye, becomes localized at the posterior pole and is incorporated into the pole cells. This is dependent on Oskar, a key factor for pole cell determination, and suggests a role for Faf in germ cell differentiation and(More)
