视网膜母细胞瘤样蛋白2抗体概述：

B淋巴细胞在抗原的刺激下，能够分化、增殖形成具有针对这种抗原分泌特异性抗体的能力。B细胞的这种能力和量是有限的，不可能持续分化增殖下去，因此产生免疫球蛋白的能力也是极其微小的。将这种B细胞与非分泌型的骨髓瘤细胞融合形成杂交瘤细胞，再进一步克隆化，这种克隆化的杂交瘤细胞是既具有瘤细胞的无限分裂的能力，又具有产生特异性抗体的B淋巴细胞的能力。将这种克隆化的杂交瘤细胞进行培养或注入小鼠腹水内即可获得大量的高效、单一的特异性抗体。这种技术即称为单克隆抗体技术。

产品介绍 Two retinoblastoma related proteins, p107 and pRb2 / p130, which are structurally and functionally similar to the product of the retinoblastoma gene (pRb / p105), were cloned by taking advantage of their ability to bind transforming proteins of DNA tumor viruses through a particular region called the "pocket domain." Like pRb, both proteins play a fundamental role in growth control. These Rb family proteins were measured in a variety of lung neoplasms. The highest percentage of undetectable levels and the tightest inverse correlation with the histological grading and with PCNA expression in the most aggressive tumor types were found for pRb2 / p130, which may suggest an important role for this protein in the pathogenesis and progression of lung cancer.

Function : Key regulator of entry into cell division. Directly involved in heterochromatin formation by maintaining overall chromatin structure and, in particular, that of constitutive heterochromatin by stabilizing histone methylation. Recruits and targets histone methyltransferases SUV420H1 and SUV420H2, leading to epigenetic transcriptional repression. Controls histone H4 'Lys-20' trimethylation. Probably acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. Potent inhibitor of E2F-mediated trans-activation, associates preferentially with E2F5. Binds to cyclins A and E. Binds to and may be involved in the transforming capacity of the adenovirus E1A protein. May act as a tumor suppressor.

Subunit : Interacts with AATF. Interacts with SUV420H1, SUV420H2 and USP4 (By similarity). Component of the DREAM complex (also named LINC complex) at least composed of E2F4, E2F5, LIN9, LIN37, LIN52, LIN54, MYBL1, MYBL2, RBL1, RBL2, RBBP4, TFDP1 and TFDP2. The complex exists in quiescent cells where it represses cell cycle-dependent genes. It dissociates in S phase when LIN9, LIN37, LIN52 and LIN54 form a subcomplex that binds to MYBL2. Interacts with RINT1.

Subcellular Location : Nucleus.

Post-translational modifications : During G0 and early G1 phase of the cell cycle, phosphorylated on Ser-639 and on 5 sites within the domain B. Phosphorylation on 视网膜母细胞瘤样蛋白2抗体Ser-672 in G1 leads to its ubiquitin-dependent proteolysis.

Similarity : Belongs to the retinoblastoma protein (RB) family.
