A New Mint1 Isoform, but Not the Conventional Mint1, Interacts with the Small GTPase Rab6
Small GTPases of the Rab family are important regulators of a large variety of different cellular functions such as membrane organization and vesicle trafficking. They have been shown to play a role in several human diseases. One prominent member, Rab6, is thought to be involved in the development of Alzheimer's Disease, the most prevalent mental disorder worldwide. Previous studies have shown ...
متن کاملRab6 interacts with the mint3 adaptor protein.
The Rab6 GTPase regulates a retrograde transport route connecting endosomes and the endoplasmic reticulum (ER) via the Golgi apparatus. Recently it was shown that active (GTP-loaded) Rab6A regulates intracellular processing of the amyloid precursor protein (APP). To characterize the role of Rab6A in APP trafficking and to identify effector proteins of the active Rab6A protein, we screened a hum...
متن کاملHigh-throughput screen for small molecule inhibitors of Mint1-PDZ domains.
Several hundred PDZ (postsynaptic density-95, Drosophila disks-large, ZO-1) domain-containing proteins have been identified in the human genome. PDZ domains play a critical role in organization and function of cellular signaling pathways. Thus, small molecule inhibitors of PDZ domain association with their targets have wide potential applications as research and therapeutic agents. PDZ domains ...
متن کاملAutoinhibition of Mint1 adaptor protein regulates amyloid precursor protein binding and processing.
Mint adaptor proteins bind to the amyloid precursor protein (APP) and regulate APP processing associated with Alzheimer's disease; however, the molecular mechanisms underlying Mint regulation in APP binding and processing remain unclear. Biochemical, biophysical, and cellular experiments now show that the Mint1 phosphotyrosine binding (PTB) domain that binds to APP is intramolecularly inhibited...
متن کاملThe Mitotic Arrest Deficient Protein MAD2B Interacts with the Small GTPase RAN throughout the Cell Cycle
BACKGROUND Previously, we identified the mitotic arrest deficient protein MAD2B (MAD2L2) as a bona fide interactor of the renal cell carcinoma (RCC)-associated protein PRCC. In addition, we found that fusion of PRCC with the transcription factor TFE3 in t(X;1)(p11;q21)-positive RCCs results in an impairment of this interaction and, concomitantly, an abrogation of cell cycle progression. Althoug...
