  • 简介:神经生长禁止的因素(GIF),metallothionein家庭的一个成员(metallothionein-3,MT3),由它的不同神经生长众所周知禁止的活动,它没被另外的MTisoforms显示出。到现在为止,然而,人们仍然不清楚地知道GIF怎么施加它的生物功能。因为GIF力量用作没有scavenger,这被报导了并且与锌的版本有关,我们的学习被与没有施主的SNOCa类型学习人的GIF和人的MT1g的反应集中于GIF和号码的相互作用,GIF是比向SNOC的MT-1g更反应的,这被发现。为了进一步弄明白,如果在这反应的GIF的高反应源于酸硷的催化作用,几异种被构造:E23K,E41G/E43A,E23K/E41G/E43A。由向SNOC学习他们的基本性质和反应,GIF的S-nitrosylation与酸硷的催化作用有关,这被发现不仅,而且到metal-thiolate簇的可接近性。
