    DLL4/Delta-like 4 概述&蛋白信息

    DLL4/Delta-like 4 研究背景

    基因概述: This DLL4 gene is a homolog of the Drosophila delta gene. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. [provided by RefSeq, Jul 2008]
    General information above from NCBI
    亞單位結構: Binds to Notch-1 and Notch-4. {ECO:0000250}.
    結構域: The Delta-Serrate-Lag2 (DSL) domain is required for binding to the Notch receptor.
    亞細胞定位: Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}.
    組織特異性: Expressed in vascular endothelium.
    翻譯後修飾: Ubiquitinated by MIB (MIB1 or MIB2), leading to its endocytosis and subsequent degradation. {ECO:0000250}.
    相似的序列: Contains 1 DSL domain. {ECO:0000255|PROSITE-ProRule:PRU00377}.; Contains 8 EGF-like domains. {ECO:0000255|PROSITE-ProRule:PRU00076}.

    Delta-like protein 4 (DLL4, Delta4), a type I membrane-bound Notch ligand, is one of five known Notch ligands in mammals and interacts predominantly with Notch 1, which has a key role in vascular development. Recent studies yield substantial insights into the role of DLL4 in angiogenesis. DLL4 is induced by vascular endothelial growth factor (VEGF) and acts downstream of VEGF as a 'brake' on VEGF-induced vessel growth, forming an autoregulatory negative feedback loop inactivating VEGF. DLL4 is downstream of VEGF signaling and its activation triggers a negative feedback that restrains the effects of VEGF. Attenuation of DLL4/Notch signaling results in chaotic vascular network with excessive branching and sprouting. DLL4 is widely distributed in tissues other than vessels including many malignancies. Furthermore, the molecule is internalized on binding its receptor and often transported to the nucleus. In pathological conditions, such as cancer, DLL4 is up-regulated strongly in the tumour vasculature. Blockade of DLL4-mediated Notch signaling strikingly increases nonproductive angiogenesis, but significantly inhibits tumor growth in preclinical mouse models. In preclinical studies, blocking of DLL4/Notch signaling is associated with a paradoxical increase in tumor vessel density, yet causes marked growth inhibition due to functionally defective vasculature. Thus, DLL4 blockade holds promise as an additional strategy for angiogenesis-based cancer therapy.
