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
Lipoma preferred partner (LPP) is a proline rich LIM domain family protein highly expressed at plasma membrane dense bodies and focal adhesions in smooth muscle cells.(1) Using the C-terminus of LPP as bait in a yeast two hybrid system, palladin, an actin-associated protein was identified. The
A major cytogenetic subgroup of lipomas is characterized by recurrent chromosome aberrations, mainly translocations, that involve chromosome segment 12q13-q15. Multiple chromosomes have been found as the translocation partners of chromosome 12 but 3q27-q28 is preferentially involved. In previous
The thyroid receptor interacting protein-6 (TRIP6) was first identified as a ligand-dependent binding partner for the thyroid hormone receptor in a yeast two-hybrid screen. A partial TRIP6 cDNA clone that was isolated in the initial screen encodes two copies of the LIM domain. The LIM domain is a
The mixed lineage leukemia, MLL, gene is frequently rearranged in patients with secondary leukemia following treatment with DNA topoisomerase II inhibitors. By FISH and Southern blot analyses we identified a rearrangement in the MLL gene due to a novel t(3;11)(q28;q23) chromosomal translocation in a
The high frequency of the t(3;12)(q27 approximately 28; q14 approximately 15) in lipomas and pulmonary chondroid hamartomas (PCHs) makes the HMGA2-LPP fusion gene the most frequent fusion gene in human tumors. We analyzed 11 PCHs with a t(3;12)(q27 approximately 28;q14 approximately 15) for the
Protein-protein interactions play an important role in the specificity of cellular signaling cascades. By using the yeast two-hybrid system, a specific interaction was identified between the second PDZ domain of the cytosolic protein tyrosine phosphatase hPTP1E and a novel protein, which was termed
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
Hearing loss is a debilitating disorder that impairs language acquisition, resulting in disability in children and potential isolation in adulthood. Its onset can have a genetic basis, though environmental factors, which are often preventable, can also cause the condition. The genetic forms are
LIM and SH3 domain protein (LASP-1) is a specific focal adhesion protein involved in cell migration. Overlay studies demonstrate that LASP-1 directly binds to the proline-rich domains of zyxin, lipoma preferred partner (LPP), and vasodilator-stimulated phosphoprotein (VASP), with zyxin being the
