资源简介:
NF2 (Merlin) is a product of the tumor suppressor gene neurofibromatosis type 2 (NF2). NF2 binds to the PBD of PAK1 and prevents its activation (Kissil et al. 2003). In primary schwannoma tumor samples derived from patients with germline mutations in the NF2 gene, PAK1 activity is highly elevated (Yi et al. 2008) and essential for the malignant growth of NF2-deficient cells (Hirokawa et al. 2004). In complex with ERBIN (ERBB2IP), NF2 may also be involved in the inhibition of PAK2 activation (Wilkes et al. 2009).<p><br>The localization and function of NF2 may be modulated by PAK2-mediated phosphorylation and subsequent sumoylation (Rong et al. 2004, Qi et al. 2014).
NF2(Merlin)是神经纤维瘤病2型(NF2)抑癌基因的产物。NF2与PAK1的PD结构域结合,从而阻止其激活(Kissil等,2003年)。在来自携带NF2基因胚系突变的原发性神经鞘瘤肿瘤样本中,PAK1活性显著升高(Yi等,2008年),这对于NF2缺陷细胞的恶性生长至关重要(Hirokawa等,2004年)。NF2与ERBIN(ERBB2IP)形成的复合物可能还参与了PAK2激活的抑制(Wilkes等,2009年)。NF2的定位和功能可能受到PAK2介导的磷酸化和随后的泛素化修饰的调节(Rong等,2004年,Qi等,2014年)。
