WebMar 16, 2024 · However, using the conformation of EphA4 when bound to ephrin-a5, in one low-energy binding pose (Figure 1 D), the ligand recapitulated several of the binding interactions produced by the binding loop from the ephrin ligand (Figure 1 E). In this pose, the backbone of 123C4 adopted a compact type I β-turn conformation, characterized by … WebNov 22, 2011 · Eph 体和Ephrin配体能够在同一种神经元（如海马CA1 区的锥体细胞 [10] ）内表达，有些也能够分布于同一 区域，如 EphA4、EphA7、EphB2、EphB3 EphrinB2都分布在中心突触的突触后区域 [11 13]，与它们结合 到突触PDZ 结构域蛋白的位置相一致 [11] 。
WebDec 1, 2001 · EphA4 is predominantly localized to delaminating and migrating Pax-7-positive muscle precursors whereas ephrin-A5 is primarily distributed in the forelimb mesoderm. The expression patterns of these factors suggests that they could play multiple roles in early muscle development. WebEphrin-A4 is a 201 aa polypeptide with a 22 aa signal sequence and a 179 aa mature segment. 18 The mature protein has one potential N-linked glycosylation site and seven cysteines. Ephrin-A4 binds to EphA4 with a Kd = 5 nM and to EphB1 with a Kd = 20 nM. 18 Mouse and human ephrin-A4 show 86% aa identity in the mature segment. 12
WebEphA4 is enriched on dendritic spines of pyramidal neurons in the adult mouse hippocampus, and ephrin-A3 is localized on astrocytic processes that envelop spines. Activation of EphA4 by ephrin-A3 was found to induce spine retraction, whereas inhibiting ephrin/EphA4 interactions distorted spine shape and organization in hippocampal slices. WebJul 14, 2005 · In the present study, we report the postnatal expression of ephrin-B3 in myelinating oligodendrocytes in the mouse spinal cord. We further demonstrate that postnatal EphA4-positive cortical neurons retain their sensitivity to the ephrin-B3 in myelin and that this ligand accounts for a fraction of the inhibitory activity in CNS myelin …
WebMay 19, 2008 · The EphA4 ligand ephrin-A3 ( 601381) was localized to astrocytic processes that envelop spines. Activation of EphA4 by ephrin-A3 was found to induce spinal retraction and reduce spine density, and inhibiting the interaction distorted spine shape and organization.
