The LPP gene is the preferred translocation partner of the HMGIC gene in a subclass of human benign mesenchymal tumors known as lipomas. Here we have characterized the LPP gene product that shares 41% of sequence identity with the focal adhesion protein zyxin. LPP localizes in focal adhesions as well as in cell-to-cell contacts, and it binds VASP, a protein(More)
BACKGROUND At sites of cell adhesion, proteins exist that not only perform structural tasks but also have a signaling function. Previously, we found that the Lipoma Preferred Partner (LPP) protein is localized at sites of cell adhesion such as focal adhesions and cell-cell contacts, and shuttles to the nucleus where it has transcriptional activation(More)
Terminal deletions of chromosome 10p result in a DiGeorge-like phenotype that includes hypoparathyroidism, heart defects, immune deficiency, deafness and renal malformations. Studies in patients with 10p deletions have defined two non-overlapping regions that contribute to this complex phenotype. These are the DiGeorge critical region II (refs 1, 2), which(More)
Previous studies have established that the novel neuroendocrine-specific NSP gene encodes three carboxy-terminally overlapping proteins, NSP-A, NSP-B and NSP-C which are anchored to membranes of the endoplasmic reticulum. Here, we report results of studies in which expression of NSP-A in rat brain was investigated. Immunization of mice with a bacterial(More)
Targeting of proteins to a particular cellular compartment is a critical determinant for proper functioning. LPP (LIM-containing lipoma-preferred partner) is a LIM domain protein that is localized at sites of cell adhesion and transiently in the nucleus. In various benign and malignant tumors, LPP is present in a mutant form, which permanently localizes the(More)
7B2 is a neuroendocrine chaperone interacting with the prohormone convertase PC2 in the regulated secretory pathway. Its gene is located near the Prader-Willi syndrome (PWS) region on chromosome 15. In a previous study we were able to show 7B2 immunoreactivity in the supraoptic nucleus (SON) or the paraventricular nucleus (PVN) in only three of five PWS(More)
PEA3 is a member of a subfamily of ETS domain transcription factors which is regulated by a number of signaling cascades, including the mitogen-activated protein (MAP) kinase pathways. PEA3 activates gene expression and is thought to play an important role in promoting tumor metastasis and also in neuronal development. Here, we have identified the LIM(More)
A new member of the proprotein convertase gene family (LPC) has been identified at a chromosome translocation breakpoint occurring in a high grade lymphoma. The translocation t(11;14)(q23;q32) has been molecularly cloned and shown to be the result of a fusion between an intron in the 3' -untranslated region of LPC with a sequence close to the switch region(More)
PLAG1, a novel developmentally regulated C2H2 zinc finger gene, is consistently rearranged and overexpressed in pleomorphic adenomas of the salivary glands with 8q12 translocations. In this report, we show that PLAG1 is a nuclear protein that binds DNA in a specific manner. The consensus PLAG1 binding site is a bipartite element containing a core sequence,(More)
Wolfram syndrome (WS) is characterized by optic atrophy, insulin-dependent diabetes mellitus, vasopressin (VP)-sensitive diabetes insipidus, and neurosensory hearing loss. Here we report a disturbance in VP precursor processing in the supraoptic and paraventricular nuclei of WS patients. In these patients with diabetes insipidus we could hardly detect any(More)
