PDZ结构域PDZK4蛋白抗体的多样性：

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 PDZK4, also known as PDZRN4L (PDZ domain-containing RING finger protein 4-like protein) or LU1, is a 769 amino acid coiled-coil protein that contains one PDZ (DHR) domain. Encoded by a gene that maps to human chromosome Xq28, PDZK4 is conserved in dog, cow, mouse, rat and zebrafish. PDZK4 localizes to cytoplasm and is expressed specifically in adult and fetal brain. PDZK4 functions as an oncogene and is up-regulated in synovial carcinomas. Treatment of synovial sarcoma cells with small interfering RNA (siRNA) inhibits PDZK4 expression, resulting in tumor-cell growth suppression, suggesting that inappropriate expression of PDZK4 may play a role synovial sarcoma cell proliferation.

The exact function of FRMPD2 is unknown. The protein contains a FERM domain: such structures are often involved in signal transduction pathways. Alternatively spliced transcript variants encoding different isoforms have been identified.

Function : May play a role in the regulation of tight junction formation. Binds phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P2). 

Subunit : Interacts (via the PDZ 2 domain) with CTNND2 (via the extreme C-terminus). Interacts (via the PDZ 2 domain) with PKP4 (via the extreme C-terminus); this interaction directed FRMPD2 to the basolateral membranes. Interacts (via the PDZ 2 domain) with ARVCF (via the extreme C-terminus). 

Subcellular Location : Cytoplasm (Potential). Basolateral cell membrane. Cell junction, tight junction. Note=Colocalizes with CTNNB1, CDH1 and PKP4 at the basolateral membrane. Colocalizes with TJP1 at tight junctions. Its recruitment to cell-cell contacts requires CDH1. 

Tissue Specificity : Expressed in epithelial cells. 

Similarity : Contains 1 FERM domain. 

Contains 1 KIND domain. 

Contains 3 PDZ (DHR) domains.
