In this issue, Malhotra and colleagues use biochemical approaches to identify a new class of secretory cargo carriers (CARTS) that do not contain the larger cargoes, collagen or Vesicular stomatitis virus (VSV)-G glycoprotein. CARTS appear to be basolateral membrane-directed carriers that use myosin for their motility but not for their formation.
在本期中,Malhotra 及其同事使用生化方法鉴定了一类新的分泌货物载体 (CARTS),这些载体不包含较大的货物,如胶原蛋白或 Vesicular stomatitis virus (VSV)-G 糖蛋白。CARTS 似乎是基底外侧膜定向载体,它们使用肌球蛋白进行运动,但不用于其形成。
