basic FUNCTION
| determining and maintaining the regional specificity along the dorsal ventral (anteroposterior) axis of retina |
|
may serve as an important BMP regulator for differentiating mesenchymal cells, especially during skeletogenesis, and for developing specific neurons  |
|
may function as a modulator of BMP signaling during embryonic development  |
|
plays a role in regulating angiogenesis  |
|
reduces BMP7 signaling in healthy renal proximal tubules, and the loss of this activity upon sloughing of injured epithelia promotes BMP7 signaling in repopulating, dedifferentiated epithelia  |

requirement for ventroptin during eye anterior segment development  |
