Specificity / Sensitivity

Phospho-M-CSF Receptor (Tyr708) Antibody detects transfected levels of M-CSF receptors only when phosphorylated at Tyr708. This antibody may cross-react with other activated protein tyrosine kinases including insulin and EGF receptors.

磷酸化M-CSF 受体 (Tyr708)的抗体仅在M-CSF 受体的Tyr708位点磷酸化时能检测到转染表达的M-CSF 受体蛋白。本抗体能与其它激活的酪氨酸激酶,包括胰岛素和EGF受体等,发生交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr708 of human M-CSF receptor. Antibodies are purified by protein A and peptide affinity chromatography.

多克隆抗体通过用多肽免疫动物得到,该磷酸化多肽是根据人的M-CSF 受体蛋白Tyr708附近的氨基酸序列合成的。抗体经过protein A和亲和层析纯化。

Macrophage-colony stimulating factor (M-CSF, CSF-1) receptor is an integral membrane tyrosine kinase encoded by the c-fms proto-oncogene. M-CSF receptor is expressed in monocytes (macrophages and their progenitors) and drives growth and development of this blood cell lineage. (1-3). Binding of M-CSF to its receptor induces receptor dimerization, activation and autophosphorylation of cytoplasmic tyrosine residues used as docking sites for SH2-containing signaling proteins (4). There are at least five major tyrosine autophosphorylation sites. Tyr723 (Tyr721 in mouse) is located in the kinase insert (KI) region. Phosphorylated Tyr723 binds the p85 subunit of PI3 kinase as well as PLC-γ 2 (5). Phosphorylation of Tyr809 provides a docking site for Shc (5). Overactivation of this receptor can lead to a malignant phenotype in various cell systems (6). The activated M-CSF receptor has been shown to be a predictor of poor outcome in advanced epithelial ovarian carcinoma (7) and breast cancer (8).

巨噬细胞集落刺激因子(M-CSF, CSF-1)受体是由原癌基因c-fms编码的一种膜嵌合的酪氨酸激酶。M-CSF 受体表达在单核细胞(巨噬细胞及其前体细胞)上并促进这一系列血细胞的生长和发育(1-3)。M-CSF和它的受体结合后会引起受体二聚化、激活、以及细胞质内作为含SH2信号蛋白结合位点的酪氨酸残基自磷酸化(4)。至少有5个主要的酪氨酸自磷酸化位点。Tyr723 (小鼠Tyr721)位于激酶插入(KI)区。磷酸化的Tyr723能够与PI3K激酶的p85亚基以及PLC-γ 2结合(5)。磷酸化的Tyr809能够为Shc提供停泊位点(5)。该受体的过度激活会导致各种细胞体系呈现出恶性特征(6)。激活的M-CSF 受体表明晚期上皮样卵巢癌(7)和乳腺癌预后不良(8)。

Tyr708 (Tyr706 in mouse) is located inthe KI region of M-CSF receptor. Phosphorylation of Tyr708 may influence the binding of PI3 kinase to the activated M-CSF receptor (9).

Tyr708(小鼠Tyr706) 位于M-CSF受体的KI(激酶插入)区。Tyr708的磷酸化可能影响PI3K激酶结合到活化的M-CSF受体(9)。
