PBX1 is a homeodomain protein that functions in complexes with other homeodomain-containing proteins to regulate gene expression during developmental and/or differentiation processes. A yeast two-hybrid screen of a fetal liver-hematopoietic cDNA library using PBX1a as bait led to the discovery of a novel non-homeodomain-containing protein that interacts(More)
Endocytosis of receptors at the plasma membrane is controlled by a complex mechanism that includes clathrin, adaptors, and actin regulators. Many of these proteins are conserved in yeast yet lack observable mutant phenotypes, which suggests that yeast endocytosis may be subject to different regulatory mechanisms. Here, we have systematically defined genes(More)
