ABSTRACT
We have previously reported Foxk1 as an important transcription factor in the myogenic progenitors. SWI-independent-3 (Sin3) has been identified as a Foxk1 binding candidate using a yeast two-hybrid screen. In the present study, we have identified the Foxk1 N-terminal (1-40) region as the Sin3 interacting domain (SID), and the PAH2 of Sin3 as the Foxk1 binding domain utilizing yeast two-hybrid and GST pull-down assays. Further studies revealed that knockdown of Sin3a or Sin3b results in cell cycle arrest and upregulation of cell cycle inhibitor genes. In summary, our present studies have shown that Foxk1 interacts with Sin3 through the SID and that Sin3 has an important role in the regulation of cell cycle kinetics of the MPC population. The results of these studies continue to define and assemble the networks that regulate the MPCs and muscle regeneration.

    In yeast, the G1 cyclin Cln3 promotes cell cycle entry by activating the transcription factor SBF. In mammals, there is a parallel system for cell cycle entry in which cyclin dependent kinase (CDK) activates transcription factor E2F/Dp. Here we show that Cln3 regulates SBF by at least two...

    PC3/Tis21 is a transcriptional cofactor that inhibits proliferation in several cell types, including neural progenitors. Here, we report that PC3/Tis21 associates with HDAC1, HDAC4, and HDAC9 in vivo, in fibroblast cells. Furthermore, when HDAC1, HDAC4, or HDAC9 are silenced in fibroblasts or in...

    STRA13 is a hypoxia-inducible bHLH transcription factor implicated in the pVHL/HIF, TGF-beta, and Jak/STAT pathways. To further characterize the STRA13 protein-interacting network and mechanisms of STRA13-dependent transcription, we utilized yeast two-hybrid screening. Here we report on STRA13...

    To explore mechanisms for specificity of function within the family of E2F transcription factors, we have identified proteins that interact with individual E2F proteins. A two-hybrid screen identified RYBP (Ring1- and YY1-binding protein) as a protein that interacts specifically with the E2F2...

    The article investigates the diversity of the interactions between host cell factor-1 (HCF-1) and E2F proteins and the variety of multi-protein complexes it occurs in. It also explores how HCF-1 is intimately associated with transcriptional regulation of E2F-responsive promoters. It discusses...

    E2F is a family of transcription factors implicated in cell cycle control. To understand the role of E2F in controlling cell cycle progression, it is necessary to clarify the breadth of the E2F family. To date, seven E2F subunits have been identified. We report here the characterization of a new...

    Checkpoint controls ensure the completion of cell cycle events with high fidelity in the correct order. Here we show the existence of a novel checkpoint that ensures coupling of cell wall synthesis and mitosis. In response to a defect in cell wall synthesis, S. cerevisiae cells arrest the...

    Members of the E2F family of transcription factors play an important role in regulating the cell cycle, and their activity is often perturbed during the development of human malignancies. More recent work has shown that E2F-1 regulates apoptosis as well as proliferation, in part by stabilizing...
