The TRAP (thyroid hormone receptor-associated proteins) transcription coactivator complex (also known as Mediator) was first isolated as a group of proteins that facilitate the function of the thyroid hormone receptor. This complex interacts physically with several nuclear receptors through the TRAP220 subunit, and with diverse activators through other(More)
The TRAP/Mediator complex serves as a coactivator for many transcriptional activators, including nuclear receptors such as the thyroid hormone receptor (TR) that targets the TRAP220 subunit. The critical but selective function of TRAP220 is evidenced by the embryonic lethal phenotype of Trap220(-)(/)(-) mice and by the observation that Trap220(-)(/)(-)(More)
TDP-43 pathology is a disease hallmark that characterizes amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD-TDP). Although a critical role for TDP-43 as an RNA-binding protein has emerged, the regulation of TDP-43 function is poorly understood. Here, we identify lysine acetylation as a novel post-translational modification(More)
Lysine acetylation has emerged as a dominant post-translational modification (PTM) regulating tau proteins in Alzheimer's disease (AD) and related tauopathies. Mass spectrometry studies indicate that tau acetylation sites cluster within the microtubule-binding region (MTBR), a region that is highly conserved among tau, MAP2, and MAP4 family members,(More)
Tau proteins are abnormally aggregated in a range of neurodegenerative tauopathies including Alzheimer's disease (AD). Recently, tau has emerged as an extensively post-translationally modified protein, among which lysine acetylation is critical for normal tau function and its pathological aggregation. Here, we demonstrate that tau isoforms have different(More)
Multiple endocrine neoplasia type 1 (MEN1) is a dominantly inherited tumor syndrome that results from the mutation of the MEN1 gene that encodes protein menin. Stable overexpression of MEN1 has been shown to partially suppress the RAS-mediated morphological changes of NH3 fibroblast cells. Little is known about the molecular mechanisms by which menin(More)
