摘要： Regulation of the number of activin receptors that are present in the cell membrane plays a key role in the modulation of cellular responses to activin.In order to find the regulators, a novel protein ARIPzip, interacting with activin type Ⅱ receptors, was searched and identified by using yeast two-hybrid screening.ARIPzip is a splicing variant of ARIP2.This has been discussed previously.ARIPzip can specifically interact with ActR Ⅱ A, and is widely distributed in mouse tissues.Overexpression of ARIPzip can cause the activin-induced transcriptional activities to increase in a dose-dependent manner while the overexpression of ARIP2 can decrease these activities.These data suggest that the C-terminal regions of ARIP2 and ARIPzip are involved in the regulation of activin signaling.
