描述：

LIMK1 Antibody检测内源性非磷酸化的LIMK1总蛋白。该抗体不能与LIMK2蛋白发生交叉反应。通过人工合成人源LIMK1蛋白羧基末端周围相应多肽片段去免疫动物从而制备出多克隆抗体。通过蛋白A和多肽亲和层析纯化抗体。LIM激酶(LIMK1 and LIMK2)是丝氨酸/苏氨酸激酶，该蛋白在它们的氨基端调节区域含有两个锌指结构其被认为是LIM结构(1)。Rho-family GTPases, PAKs和ROCK的下游的LIM激酶涉及肌动蛋白细胞骨架调节(2,3)。PAKs和ROCK激酶使LIMK1或LIMK2蛋白在激活环里保守的Thr508 或Thr505位点磷酸化，这增加了LIMK活性(3-5)。通过在cofilin蛋白的氨基末端Ser3位点残基磷酸化，活化的LIM 激酶抑制cofilin蛋白的肌动蛋白解聚活性 (6,7)。

原厂资料：

Specificity / Sensitivity

LIMK1 Antibody detects endogenous levels of total LIMK1 protein independent of phosphorylation. The antibody does not cross-react with LIMK2.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal residues of human LIMK1. Antibodies are purified by protein A and peptide affinity chromatography.

Background

LIM kinases (LIMK1 and LIMK2) are serine/threonine kinases that have two zinc finger motifs, known as LIM motifs, in their amino-terminal regulatory domains (1). LIM kinases are involved in actin cytoskeletal regulation downstream of Rho-family GTPases, PAKs and ROCK (2,3). PAK1 and ROCK phosphorylate LIMK1 or LIMK2 at the conserved Thr508 or Thr505 residues in the activation loop, increasing the LIMK activity (3-5). Activated LIM kinases inhibit the actin depolymerization activity of cofilin by phosphorylation at the amino-terminal Ser3 residue of cofilin (6,7).
