类脊索蛋白1 (Neuralin-1) (Neurogenesin-1) (Ventroptin)

Q9BU40

功能描述

通过结合BMP4并阻止其与受体相互作用,从而拮抗BMP4的功能。改变神经干细胞的命运定型,从胶质细胞发生转向神经发生。通过阻止神经干细胞采用胶质细胞命运,促进脑内神经干细胞的神经元分化。可能在背腹轴形成中起关键作用。可能在胚胎骨骼形成中起作用 (By similarity)。可能还通过调节内皮细胞中BMP4的作用,在调节视网膜血管生成中发挥重要作用。在前段眼部发育过程中起作用。 {ECO:0000250, ECO:0000269|PubMed:18587495, ECO:0000269|PubMed:22284829}。
