Optical Control of Peroxisomal Trafficking
The blue-light-responsive LOV2 domain of Avena sativa phototropin1 (AsLOV2) has been used to regulate activity and binding of diverse protein targets with light. Here, we used AsLOV2 to photocage a peroxisomal targeting sequence, allowing light regulation of peroxisomal protein import. We generated a protein tag, LOV-PTS1, that can be appended to proteins of interest to direct their import to t...
متن کاملMining Neighbors' Topicality to Better Control Authority Flow
Web pages are often recognized by others through contexts. These contexts determine how linked pages influence and interact with each other. When differentiating such interactions, the authority of web pages can be better estimated by controlling the authority flows among pages. In this work, we determine the authority distribution by examining the topicality relationship between associated pag...
متن کاملControl of Vesicular Trafficking by Rho GTPases
Although vesicular trafficking is essential for a large variety of cellular processes, the regulation of vesicular trafficking is still poorly understood. Members of the Rho family of small GTPases have recently emerged as important control elements of many stages of vesicular trafficking, providing new insight into the regulation of these events. We will discuss the diverse roles played by Rho...
متن کاملCdk1-dependent control of membrane-trafficking dynamics
Cyclin-dependent kinase 1 (Cdk1) is required for initiation and maintenance of polarized cell growth in budding yeast. Cdk1 activates Rho-family GTPases, which polarize the actin cytoskeleton for delivery of membrane to growth sites via the secretory pathway. Here we investigate whether Cdk1 plays additional roles in the initiation and maintenance of polarized cell growth. We find that inhibiti...
متن کاملSynaptic Control of Secretory Trafficking in Dendrites
Localized signaling in neuronal dendrites requires tight spatial control of membrane composition. Upon initial synthesis, nascent secretory cargo in dendrites exits the endoplasmic reticulum (ER) from local zones of ER complexity that are spatially coupled to post-ER compartments. Although newly synthesized membrane proteins can be processed locally, the mechanisms that control the spatial rang...
