产品介绍 LIMK1 is a protein kinase which regulates actin filament dynamics. Phosphorylates and inactivates the actin binding/depolymerizing factor cofilin, thereby stabilizing the actin cytoskeleton. LIMK1 may be involved in brain development; it is highly expressed in both adult and fetal nervous system. Detected ubiquitously throughout the different regions of adult brain, with highest levels in the cerebral cortex. Expressed to a lesser extent in heart and skeletal muscle.
Function : Serine/threonine-protein kinase that plays an essential role in the regulation of actin filament dynamics. Acts downstream of several Rho family GTPase signal transduction pathways. Activated by upstream kinases including ROCK1, PAK1 and PAK4, which phosphorylate LIMK1 on a threonine residue located in its activation loop. LIMK1 subsequently phosphorylates and inactivates the actin binding/depolymerizing factors cofilin-1/CFL1, cofilin-2/CFL2 and destrin/DSTN, thereby preventing the cleavage of filamentous actin (F-actin), and stabilizing the actin cytoskeleton. In this way LIMK1 regulates several actin-dependent biological processes including cell motility, cell cycle progression, and differentiation. Phosphorylates TPPP on serine residues, thereby promoting microtubule disassembly. Stimulates axonal outgrowth and may be involved in brain development. Isoform 3 has a dominant negative effect on actin cytoskeletal changes.
Subunit : Interacts (via LIM domain) with the cytoplasmic domain of NRG1 (By similarity). Interacts with NISCH (By similarity). Interacts with RLIM and RNF6 (By similarity). Self-associates to form homodimers. Interacts with HSP90AA1; this interaction promotes LIMK1 dimerization and subsequent transphosphorylation. Interacts with CDN1C. Interacts with SSH1. Interacts with ROCK1.
Subcellular Location : Cytoplasm. Nucleus. Note=Predominantly found in the cytoplasm.
Tissue Specificity : Highest expression in both adult and fetal nervous system. Detected ubiquitously throughout the different regions of adult brain, with highest levels in the cerebral cortex. Expressed to a lesser extent in heart and skeletal muscle.
Post-translational modifications : Autophosphorylated (By similarity). Phosphorylated on Thr-508 by ROCK1 and PAK1, resulting in activation. Phosphorylated by PAK4 which increases the ability of LIMK1 to phosphorylate cofilin. Phosphorylated at Ser-323 by MAPKAPK2 during activation of VEGFA-induced signaling, which results in activation of LIMK1 and promotion of actin reorganization, cell migration, and tubule formation of endothelial cells. Dephosphorylated and inactivated by SSH1. Phosphorylated by CDC42BP. 
Ubiquitinated. 'Lys-48'-linked polyubiquitination by RNF6 leads to proteasomal degradation through the 26S proteasome, modulating LIMK1 levels in the growth cone and its effect on axonal outgrowth. Also polyubiquitinated by RLIM (By similarity).
DISEASE : Note=LIMK1 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region.
Similarity : Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. Contains 2 LIM zinc-binding domains.
Contains 1 PDZ (DHR) domain.
Contains 1 protein kinase domain.

LIM激酶1(LIMkinase1,LIMK-1)是单丝氨酸蛋白激酶,LIMK-1的活化受多种机制调控,成为联系细胞外刺激与细胞骨架稳定性的枢纽,在多种基本的生物学过程中起重要作用。LIMK-1包含LIM和PDZ蛋白和蛋白相互作用区、P/S结构域、激酶结构域,在神经元中呈高表达。它的主要作用是使肌动蛋白解聚因子cofilin磷酸化和失活,从而导致肌动蛋白细胞骨架的改变。

抗体的生活习性：
(1)结合特异性抗原：抗体与其他免疫球蛋白分子区别，就在于抗体能与相应抗原发生特异性结合，在体内导致生理或病理效应;在体外产生各种直接或间接的可见的抗原抗体结合反应。抗体是靠其分子上的特殊的结合部位与抗原结合的。
(2)激活补体：抗体与相应抗原结合后，借助暴露的补体结合点去激活补体系统、激发补体的溶菌、溶细胞等免疫作用。
(3)结合细胞：不同类别的免疫球蛋白，可结合不同种的细胞，产生不同的疚，参与免疫应答。
(4)可通过胎盘及粘膜：免疫球蛋白G(IgG)能通过胎盘进入胎儿血流中，使胎儿形成自然被动免疫。免疫球蛋白A(IgA)可通过消化道及呼吸道粘膜，是粘膜局部抗感染免疫的主要因素。
(5)具有抗原性：抗体分子是一种蛋白质，也具有刺激机体产生免疫应答的性能。不同的免疫球蛋白分子，各具有不同的抗原性。
(6)抗体对理化因子的抵抗力与一般球蛋白相同：不耐热，60～70℃即被破坏。各种酶及能使蛋白质凝固变性的物质，均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白，再经透析法将其纯化。
一抗和二坑的区别：
第一抗体就是平常所说的抗体，即能和抗原特异性结合。
第二抗体是能和抗体结合的，即抗体的抗体。主要用于检测抗体的存在。
一抗是针对抗原的抗体，二抗是针对一抗的抗体。即抗体也可以充当抗原刺激机体产生抗体。也就是说，抗原进入机体刺激机体免疫系统产生免疫应答，由B细胞可以产生与相应抗原发生特异性结合的特殊蛋白质。
一抗二抗都是一种可以特异结合别的物质的基团，而且一抗可以至少结合两种其他基团（底物和二抗）。
一抗：可以特异结合底物，就是识别出我们想要检测的东西。一抗和底物结合与否用肉眼是看不出来的。
二抗：可以和一抗结合，并带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团），作用是检测一抗。 如果一抗自己带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团），则不需要二抗。但这样成本很高，因为一种一抗只识别一种底物。所以如今的设计一般是二抗带上可检测标记，再来检测一抗。而一抗识别底物。这样，当一抗结合到底物上，就可以通过二抗检测出来。  抗体的生物素化标记实验要点：
1.如在反应混合液中有叠氮钠或游离氨基存在,会抑制标记反应。因此,蛋白质在反应前要对 0.1mol/L碳酸氢钠缓冲液或0.5mol/L硼酸缓冲液充分透析；
2.所用的NHSB及待生物素化蛋白质之间的分子比按蛋白质表面的ε-氨基的密度会有所不同,选择不当则影响标记的效率,应先用几个不同的分子比来筛选最适条件；
3.用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活；
4.由于抗体的氨基不易接近可能造成生物素化不足,此时可加入去污剂如 Triton x-100, Tween20等；
5.当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,生物素化会降低或损伤抗体蛋白的结合力或活性；
6.生物素还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及苯酚基,也可与糖基共价结合；
7.交联反应后,应充分透析,否则,残余的生物素会对生物素化抗体与亲和素的结合产生竞争作用；
8.在细胞的荧光标记实验中,中和亲和素的本底低,但由于链霉亲和素含有少量正电荷,故对某些细胞可导致高本底。
