-What I am currently doing: I am trying to understand what sequence properties proteasome likes when it comes to initiate degradation from the termini as well from an internal region in the protein.

-Why I enjoy doing science: Science is a way of thinking much more than it is a body of knowledge -Carl Sagan. I consider myself lucky to be in a profession that is full of challenges and surprises.
-When not in lab physically and mentally: Spend time with my daughter, watching something on Netflix, enjoying good food or visiting a new place.

My research philosophy is to understand biological phenomena quantitatively. By shedding light on proteasome activity using fluorescent protein sensors, I am trying to unveil the mechanisms of cellular processes such as aging.

Initiation codes may govern the behavior of physiological proteins and regulate various cellular events. My goal is to elucidate its biological significance in mammalian cells.

Frank J. Medina, PhD

Lab Manager

During graduate school, I studied different mechanisms responsible for regulating activity of proteins from the Rho family of GTPases. My postdoctoral research project focused on investigating potential mechanisms utilized by mouse mammary tumor virus to evade the innate immune response. I am now the lab manager in the Matouschek lab and get to work alongside some amazing scientists. In my free time, I like to play guitar, catch local shows and jog.

Jacob Anguiano

Undergraduate Research Assistant 

Hello my name is Jacob Dylan Anguiano. I am in my second year here at the University of Texas at Austin. I am currently studying Advertising at the Stan Richards School. I really enjoy the lab because it strays from what I am studying and really allows me to be diverse in my learning. I am glad to be here and look forward to a great semester and advancing year.

I am characterizing how arrangement of ubiquitin chain and initiation region affect degradation. In other words, how does the geometry of the degradation targeting signal modulate substrate selection by the proteasome? When not in lab you can find me hiking with my dog (Derek Shepherd), drinking cider, or playing ultimate. Find me on science twitter!

I graduated from the University of North Carolina at Chapel Hill with my B.S. in Chemistry and joined the Matouschek Lab in 2018 in pursuit of my PhD in the Institute for Cellular and Molecular Biology at the University of Texas at Austin. I study the ubiquitin proteasome system, which helps control cellular protein levels by degrading them. There are two primary components that determine if a substrate will be targeted to the proteasome: ubiquitination and a disordered initiation region. My project uses in vivo methods to study the interactions of these two targeting factors to better understand how the proteasome controls substrate specificity. In my free time I like to travel and experience new places and cultures. I also enjoy scuba diving, surfing, swimming, and playing soccer.

I'm probing the relationship between proteasome activity and the lifespan and cell cycle of individual S. Cerevisiae cells. Toward this end, I'm working on developing microfluidic devices and image analysis pipelines that can isolate and track large populations of cells throughout their lifetime. I love eating and cooking great food, going to shows, and skating around Austin.

I am an undergraduate student (class of 2020) at UT Austin majoring in Biochemistry and a member of the Polymathic Scholars program. My hometown is Clear Lake City, Texas. I am excited to learn more about the ubiquitin-proteasome system under the tutelage of the renowned Takuya Tomita. I harbor ambitions of one day starting my very own lab as a primary investigator. When I am not in lab, I enjoy reading novels, biking, surfing the Internet, and hanging out with friends and family.

I am an undergraduate student at UT majoring in Biology and minoring in Philosophy and Russian. I am looking forward to learning more about the role of geometry in the ubiquitin-proteasome system while assisting Caroline Davis with her project. One day, I would like to apply the skills gained from this lab to my own project. In my free time I like to listen to podcasts, watch movies, and try new food.

I am an undergraduate Biochemistry major at UT Austin from O’Fallon, Illinois. I assist Logan Spaller in studying the ubiquitin proteasome system to better understand how substrates are targeted to the proteasome while considering 2 primary components: ubiquitination and a disordered initiation region. After graduating with my bachelor’s, I hope to continue my education and graduate from medical school. In my free time, I like to ice skate, cook a variety of meals, spend time with friends, and snowboard when I have the opportunity.

I am an undergraduate student at UT Austin majoring in Biochemistry, with a focus on computational and physical methods. I volunteer under the mentorship of John Cooper, studying proteasome activity in relation to cell lifespan and various phenotypes of aging. Upon graduating, I hope to attend graduate school and pursue research in industry. In my free time, I can be found exploring coffee shops, watching shows, and enjoying time with family and friends.

I am an undergraduate Biochemistry major at UT Austin. I am assisting Logan Spaller in studying the ubiquitin proteasome systems, specifically how Cdc48 works in vivo to promote protein degradation. After receiving my bachelor's at UT I am planning on continuing into graduate school to pursue a Ph.D. in Biochemistry. In my free time, I enjoy watching new movies /shows, exploring new places to eat, and spending time with friends.
