The tra-1 and tra-2 sex-determining genes promote female fates in Caenorhabditis elegans. Classical genetic studies placed tra-1 as the terminal regulator of the pathway with tra-2 acting upstream as a regulator of regulators of tra-1. Here we report the surprising result that the TRA-1 transcription factor binds the intracellular domain of the TRA-2(More)
Autophagy is a membrane-mediated degradation process of macromolecule recycling. Although the formation of double-membrane degradation vesicles (autophagosomes) is known to have a central role in autophagy, the mechanism underlying this process remains elusive. The serine/threonine kinase Atg1 has a key role in the induction of autophagy. In this study, we(More)
We have identified a novel protein, protein phosphatase 1 F-actin cytoskeleton targeting subunit (phostensin). This protein is encoded by KIAA1949 and was found to associate with protein phosphatase 1 (PP1) in the yeast two-hybrid assay, co-immunoprecipitation, and GST pull-down assay. Northern blot analysis revealed that phostensin mRNA was predominantly(More)
Phostensin, a protein phosphatase 1 F-actin cytoskeleton targeting subunit encoded by KIAA1949, consists of 165 amino acids and is located between HLA-C and HLA-E gene clusters on human chromosome 6. In this current study, we characterized the biochemical functions of phostensin. Actin dynamics assays using gelsolin-actin seeds showed that phostensin(More)
