蛋白香叶烯基转移酶1α抗体的多样性：

抗体的异质性。抗体的组成极为复杂，是由成千上万、多种多样的免疫球蛋白（Ig）分子所组成。这些Ig分子在形状、大小、结构以及氨基酸的组成和排列上，既相似，又有差别。由于有差别，它们的电泳活性就有很大的变化。

因为抗体具有与抗原决定簇相对应的结合部位（抗原结合簇），所以抗体与抗原的结合具有特异性。另一方面，抗体本身是一种蛋白质，具有本身的氨基酸组成、排列和立体结构，对异种动物来说，它又是抗原。各类Ig都具有可用血清学方法检出的抗原特异性，它们表现出不同的血清学类型。

产品介绍 FNTA, also known as CAAX farnesyltransferase (FTase), attaches a farnesyl group from farnesyl pyrophosphate to cysteine residues at the fourth position from the C terminus of proteins that end in the so-called CAAX box, where C is cysteine, A is usually but not always an aliphatic amino acid, and X is typically methionine or serine. This type of posttranslational modification provides a mechanism for membrane localization of proteins that lack a transmembrane domain. This enzyme has the remarkable property of farnesylating peptides as short as four residues in length that conform to the CAAX consensus sequence. FNTA is also a specific cytoplasmic interactor of the transforming growth factor-beta and activin type I receptors. It is likely to be a key component of the signaling pathway which involves p21ras, an important substrate for farnesyltransferase.

Function : Catalyzes the transfer of a farnesyl or geranyl-geranyl moiety from farnesyl or geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. The alpha subunit is thought to participate in a stable complex with the substrate. The beta subunit binds the peptide substrate. Through RAC1 prenylation and activation may positively regulate neuromuscular junction development downstream of MUSK (By similarity). 

Subunit : Heterodimer of an alpha and a beta subunit. Interacts with MUSK; the interaction is direct and mediates AGRIN-induced phosphorylation of FNTA (By similarity). 

Subcellular Location : Cytoplasmic

Post-translational modifications : Phosphorylated. Phosphorylation is mediated by MUSK upon AGRIN stimulation and results in the activation of FNTA (By similarity). 

Similarity : Belongs to the protein prenyltransferase subunit alpha family. 

蛋白香叶烯基转移酶1α抗体Contains 5 PFTA repeats.
