Hsp70 interactions are critical for cellular viability and the response to stress. Previous attempts to characterize Hsp70 interactions have been limited by their transient nature and the inability of current technologies to distinguish direct versus bridged interactions. We report the novel use of cross-linking mass spectrometry (XL-MS) to compreh...

ABSTRACT The wound healing assay is a simple and inexpensive method that allows researchers to experimentally mimic cell growth and migration leading to wound healing. In this assay, a wound is created on a monolayer of cultured mammalian cells and cell migration is monitored. Micrographs are captured at regular intervals during the duration of the...

Historic science, technology, engineering and mathematics (STEM) disciplinary cultures were founded in a system that was predominately male, white, heterosexual, and able-bodied (i.e., “majority”). Some societal norms have changed, and so has demand for inclusive STEM engagement. However, legacy mental models, or deeply held beliefs and assumptions...

The function of the budding yeast YML018C protein remains to be determined. High-throughput studies have reported that the YML018C protein localizes to the vacuolar membrane and physically interacts with the autophagy-related protein Atg27p. While this evidence suggests a potential role for this uncharacterized protein in the process of autophagy,...

Atg27p, a single-pass transmembrane protein that functions in autophagy, localizes to a variety of cellular compartments including the pre-autophagosomal structure, late Golgi, vacuolar membrane, as well as early and late endosomes. Its cytoplasmic C-terminus contains a tyrosine sorting motif that allows for its transport to the vacuolar membrane a...

The autophagy-related protein Atg27p has been previously shown to localize to the autophagy-specific pre-autophagosomal structure (PAS) as well as to several organelles, including the late Golgi, the vacuolar membrane, and the endosome. Given that Atg27p localization to the vacuolar membrane in particular has been shown to be dependent on both its...

The common view of art and science as polar opposites along the educational spectrum can sometimes mask the degree to which they inform one another. In fact, art can also serve as a way to foster interest in querying the natural world, ultimately allowing us to recruit highly creative individuals to join the scientific community. We have experience...

In the biological sciences, students frequently equate understanding to compiling and memorizing information as a series of isolated facts. For this reason, they struggle to connect major concepts across course curriculums. In other disciplines, improvisation techniques have been introduced as a way to engage with millenials, who learn best through...

Clathrin facilitates vesicle formation during endocytosis and sorting in the trans-Golgi network (TGN)/endosomal system. Unlike in mammals, yeast clathrin function requires both the heavy (CHC) and light (CLC) chain, since Chc1 does not form stable trimers without Clc1. To further delineate clathrin subunit functions, we constructed a chimeric CHC...

Coat protein complexes contain an inner shell that sorts cargo and an outer shell that helps deform the membrane to give the vesicle its shape. There are three major types of coated vesicles in the cell: COPII, COPI and clathrin. The COPII coat complex facilitates vesicle budding from the endoplasmic reticulum (ER), while the COPI coat complex perf...

Many of the didactic tools used in the undergraduate classroom, including textbooks, often highlight science as a body of knowledge, presenting learners with a field’s current “up-to-date” understanding of a subject. It is important that students grasp the idea that this body of knowledge is not static, but evolving through a process by which scien...

We frequently use diagrams or animations to reveal to others biological phenomena that are both invisible to the naked eye and difficult to conceptualize. But these didactic tools fall short in that they generally do not provide feedback or interaction with the user, nor adapt easily to the user’s needs and abilities. Adaptability to the user’s edu...
