Screening of a Protein That Interacts with the Matrix Attachment Region-Binding Protein from Dunaliella salina

We isolated the matrix attachment region-binding protein (MBP) DMBP-1 from Dunaliella salina in our previous studies. MBPs are part of the cis-acting protein family cluster. The regulatory function possibly works through the interaction of the MBPs with each other. In the present study, DMBP-1 was used as the bait in screening the D. salina cDNA library for DMBP-1 interactors that could potenti...

MAF1, a novel plant protein interacting with matrix attachment region binding protein MFP1, is located at the nuclear envelope.

The interaction of chromatin with the nuclear matrix via matrix attachment region (MAR) DNA is considered to be of fundamental importance for chromatin organization in all eukaryotic cells. MAR binding filament-like protein 1 (MFP1) from tomato is a novel plant protein that specifically binds to MAR DNA. Its filament protein-like structure makes it a likely candidate for a structural component ...

A Myristoylated Calcium-binding Protein that Preferentially Interacts with the Alzheimer's Disease Presenilin 2 Protein

It is well established that mutations in the presenilin 1 and 2 genes cause the majority of early onset Alzheimer's disease (AD). However, our understanding of the cellular functions of the proteins they encode remains rudimentary. Knowledge of proteins with which the presenilins interact should lead to a better understanding of presenilin function in normal and disease states. We report here t...

A novel RNA-binding nuclear protein that interacts with the fragile X mental retardation (FMR1) protein.

Silenced expression of the FMR1 gene is responsible for the fragile X syndrome. The FMR1 gene codes for an RNA binding protein (FMRP), which can shuttle between the nucleus and the cytoplasm and is found associated to polysomes in the cytoplasm. By two-hybrid assay in yeast, we identified a novel protein interacting with FMRP: nuclear FMRP interacting protein (NUFIP). NUFIP mRNA expression is s...
