General annotation (Comments)
| Function | Antagonizes the function of BMP4 by binding to it and preventing its interaction with receptors. Alters the fate commitment of neural stem cells from gliogenesis to neurogenesis. Contributes to neuronal differentiation of neural stem cells in the brain by preventing the adoption of a glial fate. May play a crucial role in dorsoventral axis formation. May play a role in embryonic bone formation By similarity. May also play an important role in regulating retinal angiogenesis through modulation of BMP4 actions in endothelial cells. Plays a role during anterior segment eye development. Ref.1 Ref.6 |
| Subcellular location | Secreted Potential. |
| Tissue specificity | Expressed in the developing cornea and in the eye anterior segment in addition to the retina. Differentially expressed in the fetal brain. There is high expression in cerebellum and neocortex. Expressed in retinal pericytes. Ref.1 Ref.6 |
| Induction | By hypoxia in retinal pericytes. Ref.1 |
| Involvement in disease | Megalocornea 1, X-linked (MGC1) [MIM:309300]: An eye disorder in which the corneal diameter is bilaterally enlarged (greater than 13 mm) without an increase in intraocular pressure. It may also be referred to as anterior megalophthalmos, since the entire anterior segment is larger than normal. Features of megalocornea in addition to a deep anterior chamber include astigmatic refractive errors, atrophy of the iris stroma, miosis secondary to decreased function of the dilator muscle, iridodonesis, and tremulousness, subluxation, or dislocation of the lens. Whereas most affected individuals exhibit normal ocular function, complications include cataract development and glaucoma following lenticular dislocation or subluxation. |
| Sequence similarities | Contains 3 VWFC domains. |
| Sequence caution | The sequence AAH02909.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence AAU25841.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence BAF85795.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
